The dialing-prefix ambiguity is resolved: Anveo's own trunk edit screen has
no required-field marker on Dialing Prefix, confirming it's optional. Also
documents the separate Outbound Service Trunk vs. inbound SIP Trunk
distinction discovered while walking through a real account setup.
Confirmed against a live install's pjsip.conf/extensions.conf that every
endpoint falls back to context=intercom for messaging (message_context
blank), and that [intercom] owns one exact-match per-device dial pattern
regenerated on every dialplan rebuild. Rather than risk racing that, every
endpoint now gets message_context=sip-messaging (patched into both of Easy
Asterisk's device-creation code paths, plus a one-time migration for
existing devices), routing messages to their own [sip-messaging] context
gated on the existing pstn-permissions.conf messaging flag.

- ntfy.sh: auth-default-access was deny-all, silently blocking both publish
and anonymous subscribe on every topic once an auth-file is present.
Default to read-write (same model as public ntfy.sh) so alerts from
crowdsec.sh/pstn-trunk.sh actually get delivered.
- crowdsec.sh: add update/fresh/cancel reinstall gating — reruns previously
re-asked every optional prompt (ASN exempt, geo-allowlist, ntfy, remote
LAPI) unconditionally with no way to just refresh in place.
- asterisk-digital-ocean.sh: add optional ntfy alerts on extension
registration going offline/online, checked every 2 minutes via systemd
timer (cron.d fallback), offered on both fresh install and update.
- security-dashboard.sh: replace the outbound-only Asterisk Web Admin link
with an embedded, lazy-loaded iframe tab, with a best-effort Caddy
frame-ancestors patch and an always-available "open in new tab" fallback.
Groups: a new always-available "Groups" card in the PSTN tab (same place
as Internal SIP messaging, no dependency on a PSTN trunk being installed)
lets you name a set of extensions and bulk-enable/disable messaging for
all of them at once. Purely a management-layer convenience - pstn-groups.conf
is never read by the dialplan, which only ever looks at per-extension keys
in pstn-permissions.conf. Applying a group action just calls the same
write_messaging() each individual checkbox uses, once per current member.
Editing membership never retroactively changes anything already applied,
and deleting a group never touches members' own settings - confirmed with
tests covering create/apply/edit-membership/re-apply/delete.
Security Log: added a per-column filter row (Time/Event/Account/Remote/
Severity), live as you type, filtering client-side against the
already-fetched events rather than re-querying - persists correctly across
the existing 30-second auto-refresh.

Messaging has no dependency on a PSTN trunk existing (no cost, no
carrier, no DID), but the whole PSTN Trunk tab - including the messaging
checkbox added last commit - was hidden behind pstn_installed(), which
only becomes true once services/pstn-trunk.sh's dialplan is actually
wired in. That meant enabling messaging required going through full SIP
trunk/provider setup first for no real reason.
Added a standalone "Internal SIP messaging" card that's always visible in
the tab regardless of trunk status, backed by a new write_messaging()
that only touches the messaging key (leaving tier/allowed_numbers/
personal_did untouched) and creates pstn-permissions.conf from scratch if
it doesn't exist yet. Confirmed the systemd unit's ReadWritePaths and the
group/chmod grants already covered this - both are set up whenever a base
Asterisk install is detected, independent of pstn-trunk - so no
permission-layer changes were needed, only the dashboard's own artificial
UI gate.

get_all_permissions()/write_permission() now handle messaging alongside
tier/allowed_numbers as one save action, and the Security Dashboard's PSTN
Trunk table gets a Messaging checkbox column - no more needing to re-run
pstn-trunk.sh's CLI just to change who can use internal SIP texting,
matching how tier/allowed_numbers/personal_did already worked.
Tested that messaging correctly survives tier changes and personal-DID
assignment/removal on the same extension (independent axes, as intended).
Still explicitly not done, and said so in both READMEs rather than
implying otherwise now that there's a nice UI for it: the actual SIP
MESSAGE dialplan wiring that would make Asterisk enforce this flag. That
gap hasn't changed - only the permission storage/UI layer around it has.

Prompts now start with a 1/2/3 choice (Anveo Direct / VoIP.ms / manual)
that pre-fills already-known values - Anveo Direct's sbc.anveo.com
hostname and its 4 published signaling IPs, so they don't need retyping
from memory - plus provider-specific account-setup reminders. Every
value stays editable at each subsequent prompt; this only changes
defaults, not behavior, so existing manual-entry users see no change.
Flagged rather than silently trusted: Anveo Direct's own Outbound Trunks
page documents dialing as [PREFIX]PHONENUMBER@sbc.anveo.com, which
contradicts an earlier no-prefix-needed finding from their FAQ. The
dialplan still dials the bare number (matching the older finding) - the
quick-pick prints a loud warning to verify the Prefix field can be left
blank before relying on this, rather than guessing and hardcoding prefix
handling without live confirmation either way.

Multiple DIDs can now share one trunk/account, each assigned to a specific
extension - additive to the existing shared trunk DID/ring-group, which
keeps working unchanged for everyone regardless of what's assigned here.
- New pstn-personal-dids.conf (DID -> owner extension), read live by the
dialplan for inbound routing: a call to a personal DID routes straight
to its owner, checked against the owner's own tier/approved-numbers, no
ring-group fallback since it's that extension's own line.
- New personal_did= field per extension in pstn-permissions.conf: the
outbound Caller-ID override, used by pstn_check_busy (the shared exit
point for both domestic and international dialing) instead of the
shared trunk DID when the calling extension has one assigned.
- Both files kept in sync automatically by one write path - CLI prompt at
install/update, or a new "Personal numbers" card in the Security
Dashboard's PSTN Trunk tab - rather than requiring hand-editing both
consistently. Reassigning a DID or giving an extension a new one cleanly
drops the stale side of the old mapping.
- Assigning a DID to an internal-tier extension is accepted but warned
about (won't ring anyone until also granted full/restricted tier),
matching this repo's permissive-with-warnings style rather than
blocking the action outright.
Also fixed a real bug found while building this: security-dashboard.sh's
write_permission() did cp.remove_section(ext) whenever tier was set to
"internal", silently discarding any messaging=yes or personal_did=
already set on that extension. Now removes only the tier/allowed_numbers
keys, dropping the section only once nothing else remains in it.
Separately, de-anchored pstn-trunk.sh's install prompts from VoIP.ms as
the implicit default (provider name default, server-hostname example
wording, rate-prompt wording) now that Anveo Direct is an equally
confirmed, tested provider option.

parse_security_log() did f.readlines() on ASTERISK_LOG before slicing the
last 5000 lines - that reads the ENTIRE file into memory first. That log
is Asterisk's unrotated console/security output, and this tab polls it
every 30 seconds from the browser. Confirmed live: on a 1GB-RAM droplet
with a 1.4GB log file, this ballooned the dashboard (explicitly meant to
be a lightweight stdlib-only process) to 677MB RSS / 1.8GB peak swap,
which left CrowdSec unable to even start (boot timeout) and directly
contributed to the droplet becoming unresponsive.
Fixed by reading only a bounded ~2MB tail from the end of the file
(seek + fixed-size read) instead of the whole thing - memory use is now
constant regardless of how large the log grows. Tested against a 180MB
synthetic log: memory delta dropped from being proportional to file size
to ~7MB, in 0.05s.
Also added log rotation (services/asterisk-digital-ocean.sh) for that same
file, which had no rotation at all and reached 1.4GB in about 3 days -
copytruncate avoids needing to signal the containerized Asterisk process
to reopen its log handle.

"cscli scenarios remove crowdsecurity/asterisk_bf crowdsecurity/asterisk_user_enum"
was failing silently (stderr suppressed, "|| true" swallowed the non-zero
exit) because these scenarios are members of the crowdsecurity/asterisk
collection, and cscli refuses to remove/disable a collection member
without --force. The un-exempted hub originals kept running side-by-side
with the ASN-exempt local forks the entire time, independently banning the
same traffic with no ASN awareness at all - confirmed live by a ban
showing scenario "crowdsecurity/asterisk_bf" (the hub original) rather
than "local/asterisk_bf" (the fork) for an ASN that had just been exempted.
Fixed in two places:
- crowdsec.sh's initial setup now passes --force and surfaces a clear
warning (with the manual fix command) if it still fails, instead of
silently continuing.
- security-dashboard's set-asn-exempt.sh helper now re-asserts the forced
disable on every ASN-list save, so an install already affected by this
(from before this fix, or where the step failed for any other reason)
self-heals the next time the ASN list is edited via the dashboard,
without needing to re-run the full CrowdSec installer.

set_asn_exempt() was writing /etc/crowdsec/scenarios/local-asterisk_*.yaml
directly from the dashboard's own process, but those files are root:root
mode 644 and the secdash service user (--shell /usr/sbin/nologin) has no
write grant to them - confirmed by the reported "[Errno 13] Permission
denied" error. Every whitelist/unban attempt through the dashboard was
silently a no-op as far as CrowdSec was concerned, which is why a
carrier's IP kept getting re-banned even after repeatedly trying to
exempt its ASN.
Fixed by routing the edit through a dedicated root-owned helper script
(set-asn-exempt.sh, installed alongside app.py, root:root mode 700) that's
the one thing added to the sudoers whitelist - same pattern every other
CrowdSec-touching action here already uses (cscli via sudo), rather than
loosening the scenario files' own permissions.

- CLI country menu now asks for a per-minute rate when a country is added,
stored alongside its code/name in pstn-intl-allowed.conf. The usage-alert
script buckets each month's outbound calls into domestic vs. per-country
international (longest-code-prefix match on the dialed digits) and prices
each bucket at its own rate instead of one blended flat rate, which badly
under/over-estimated international cost.
- While the kill-switch is tripped, the periodic script now also force-hangs
up any PSTN call already in progress (docker exec + Asterisk's "channel
request hangup" against the trunk's active channels), not just new calls
- closing the gap where an in-progress call just kept running until it
ended naturally. Runs every check while tripped, not only the run that
trips it, to close a start-of-call race.
- Fixed a bug caught by testing: the hangup sweep was nested inside the
"does the call log exist" guard, so it silently never fired if the log
was missing/rotated while tripped. Moved it outside that guard.
- Documented an honest "how bulletproof is this?" breakdown in the
generated README: the provider's own real-time $0-balance block is the
actual hard ceiling (confirmed for Anveo Direct), the kill-switch here is
an estimate-based second layer, not a replacement for funding the prepaid
account at your actual risk tolerance.

- Replace the hourly cron.d spend/volume check with a per-minute systemd
timer (cron.d fallback), since it's now also the kill-switch's
enforcement point and the interval is the exposure window.
- Add a hard monthly spend-cap kill-switch: trips pstn-trunk-killswitch.conf
(read live by the dialplan, both call directions, internal calling
unaffected) once estimated spend reaches an admin-set cap, plus a loud
ntfy warning at 80% of the cap before it trips. Does not auto-reset;
clearing it is a CLI-only action (update mode) so a compromised/careless
web session can't quietly re-enable spend after a trip.
- Add a CLI-only (never web-dashboard) international-calling allow-list:
continent/country menu, always asked every run with the resulting
allow-list printed exactly once right after, optional auto-expiry with
day-of and at-expiry ntfy notices, and active re-blocking once expired.
Dialplan gates the US "011" prefix pattern on it for full-tier extensions.
- Add an independent messaging_enabled flag per extension in
pstn-permissions.conf for Asterisk's native SIP MESSAGE texting, since
the risk profile (no cost) differs from PSTN calling permissions. The
dialplan wiring to enforce it is flagged as a known gap pending live
verification against Easy Asterisk's message routing, rather than
shipping a guessed pattern.
- security-dashboard.sh: detect whether pstn-trunk is actually installed
(not just base Asterisk) and show a clear "not installed" state instead
of misleading default caps/extensions; add clickable column-header
sorting to the CrowdSec active-bans table.

Anveo Direct's "Call Security" rate-cap feature (found while evaluating
their account portal) prompted a closer look at our own NANP dialplan
pattern, which turned out to have a real gap: NANP covers Caribbean/
Atlantic nations and several US territories, not just the US - these dial
exactly like a normal 10-digit US number but bill at international/
premium rates, a well-known toll-fraud/"one-ring scam" vector precisely
because the format looks domestic. The existing _1NXXNXXXXX/_NXXNXXXXX
patterns matched all of them equally, meaning any extension (including
"full" tier) could reach premium Caribbean/territory numbers despite the
whole point of the design being "US only, no premium-rate destinations."
Verified the area code list against multiple sources rather than relying
on training-data recall alone, then added an explicit block on all 27
(Bahamas, Barbados, Anguilla, Antigua & Barbuda, British Virgin Islands,
US Virgin Islands, Cayman Islands, Bermuda, Grenada, Turks & Caicos,
Jamaica, Montserrat, Northern Mariana Islands, Guam, American Samoa, Sint
Maarten, Saint Lucia, Dominica, Saint Vincent, Puerto Rico, Dominican
Republic, Trinidad & Tobago, Saint Kitts & Nevis) - checked via REGEX()
against the extracted area code, before permission-tier checks, so it
applies regardless of tier. Tested the extraction/matching logic against
both blocked and legitimate US area codes.
Updated docs/pstn-calling-voipms-plan.md's toll-fraud reasoning, which had
previously (incorrectly) claimed NANP-only restriction alone fully closed
the cost-per-minute risk - noted as a real, live gap rather than glossing
over it. Also noted Anveo Direct's provider-side Call Security setting
(rate cap + max call duration) as a complementary backstop worth
configuring on their account portal directly, independent of this repo's
code.
VoIP.ms's one-POP-one-hostname model meant a single resolved IP was enough
for the trunk's identify match=, but Anveo Direct (researched as an
alternative after finding VoIP.ms's ToS selectively requires government ID
at signup) sends inbound signaling from a fixed set of published IPs
instead. Generalizes the pjsip include to accept multiple match= lines in
one identify object (PJSIP allows repeating it to build one match set - no
separate config objects needed per IP), with a new install prompt for any
additional known source IPs beyond the auto-resolved one.
No dial-prefix support was added despite earlier research suggesting Anveo
Direct needed one - verified against their current official FAQ (fetched
directly rather than trusting a stale search-result claim) that plain
number dialing works with no prefix.
Fixed a real bug caught while testing the update-mode round trip:
.pstn-trunk.env was written with unquoted values, which breaks `source`
entirely once any value contains a space - a multi-IP list or a
multi-word provider name (e.g. "Anveo Direct") would make bash try to run
the second word as a command. Predates this change (a multi-extension
ring group has the same shape); only surfaced by actually re-sourcing the
file and reapplying, not by inspecting generator output. Fixed by quoting
every value.
Updated docs/pstn-calling-voipms-plan.md with the Anveo Direct/DIDLogic/
SIP.US research findings and what's now implemented vs. still open
(real-time balance enforcement at Anveo specifically is unconfirmed).
Adds an inbound concurrent-call cap mirroring the existing outbound one -
outbound alone didn't protect against an inbound call-flood, which also
costs money per-minute on VoIP.ms. Both defaults bumped from 3 to 10.
Moves the cap numbers themselves out of static dialplan text and into a new
pstn-limits.conf, read live via AST_CONFIG() the same way permission tiers
already are - changing either cap takes effect on the next call, no
Asterisk restart, no reinstall. "update in place" never touches this file,
matching the existing protection for pstn-permissions.conf/.env/firewall/
Caddy config.
Adds a concurrency-caps card to security-dashboard.sh's "PSTN Trunk" tab,
above the existing permissions table, so both caps are visible and editable
from the same web page. Tested against a real running instance of the
Python app: default fallback when the file doesn't exist yet, save/persist,
invalid-input rejection, and a bash-to-Python round trip on the generated
file format.
Inbound dialplan ordering mirrors outbound's existing pattern: permission
check (is any ring-group member authorized for this caller) before the
concurrency check, consistent with outbound's tier-check-then-busy-check
order.
Reworks the outbound permission model from a flat allow-list into three
per-extension tiers (internal / restricted / full), addressing the ask for
extensions that can only reach pre-approved numbers plus extensions with
full US calling, while internal extension-to-extension dialing and ring
groups stay ungated for everyone regardless of tier.
Permissions now live in pstn-permissions.conf, read by the dialplan via
Asterisk's AST_CONFIG() on every call instead of being baked into static
dialplan text - editing that file takes effect on the next call, no
Asterisk restart and no re-running the installer. "update in place" mode
never touches this file (same protection this repo's update-mode
convention already gives .env/firewall/Caddy config); only a "fresh"
reinstall (with confirmation) or the web UI change it.
Adds a "PSTN Trunk" tab to services/security-dashboard.sh: lists every
extension (parsed from pjsip.conf) with its live tier and approved numbers,
editable with no restart - this is what makes the tier model actually
manageable day to day. Extracted the dashboard's systemd-unit writing into
its own function so "update" mode refreshes it too (previously only fresh
installs did), and generalized both the dashboard and the trunk service to
detect either asterisk-digital-ocean or the home/LAN asterisk install.
Inbound ring-group membership now checks each member's tier live per call
via an unrolled per-member dialplan block (full always rings, restricted
only if the caller's number is approved, internal never rings) rather than
a single static Dial() string.
Caught and fixed two real bugs during testing against a sandboxed vendor
copy and a live instance of the (stdlib-only) Python dashboard app:
- Asterisk Goto/GotoIf argument parsing: ring<ext>/skip<ext> are named
priorities within the same extension (declared via "same => n(label),..."),
not separate exten => entries, so jumping to them needs the single-argument
Goto(label) form - the two-argument Goto(label,1) form used initially
addresses a different, nonexistent extension named "label" instead.
- A security-relevant REGEX() direction issue: the inbound Caller-ID check
initially interpolated attacker-influenced call data into the PATTERN side
of a REGEX() match rather than the tested-string side, which would let a
crafted Caller-ID forge a match against an unrelated approved-numbers
entry. Fixed by keeping the admin-controlled approved-list as the pattern
and the live call data as the string being tested, consistently on both
the outbound and inbound checks.
Verified end-to-end: dialplan/pjsip generation and vendor-file patching
(idempotent, syntax-checked) as before, plus the new permission-file
round-trip between bash and Python, and the dashboard's new API endpoints
exercised against a real running Python server (extension parsing, tier
changes, number normalization, invalid-input rejection, atomic file writes).
Generalizes services/pstn-trunk.sh (renamed from voipms-trunk.sh in the
prior commit) away from VoIP.ms specifics - any IP-authenticated SIP
provider works, VoIP.ms is just the suggested default. Adds:
- Role-based outbound permission: a configurable allow-list of extensions
that may dial PSTN numbers (regex-gated on CHANNEL(peername)), separate
from internal extension-to-extension dialing which stays open to everyone
regardless. Blank list preserves the original "everyone can dial out"
behavior.
- Inbound ring-group: rings a configurable list of extensions instead of a
single hardcoded one.
- ntfy alerts: immediate on denied (unauthorized extension) or rejected
(concurrency cap hit) calls, plus an hourly cron-driven check that alerts
once per month when estimated spend crosses a threshold and every hour
call volume looks like a burst. Uses a self-contained pipe-delimited call
log rather than Asterisk's CDR, to avoid depending on CDR module
availability and CSV comma-quoting.
- Settings persisted to .pstn-trunk.env so "update in place" reapplies
everything from that file instead of fragile re-parsing out of generated
Asterisk config (which had a real bug: update mode was extracting the
wrong Dial(PJSIP/...) line).
Tested end-to-end against a sandboxed copy of the real vendor files:
permission-gate regex, ring-group dial-string construction, ntfy line
injection/removal, and the usage-alert script's threshold/burst/monthly-
dedup logic all verified with synthetic data. Caught and fixed a sed `&`
escaping bug in the ring-group substitution before it shipped (RING_DIAL
contains literal `&` join characters, which sed's replacement syntax
otherwise treats as "insert the match").
Renames services/voipms-trunk.sh to services/pstn-trunk.sh and generalizes
it away from VoIP.ms specifics - any IP-authenticated SIP provider works,
VoIP.ms is just the suggested default. Adds:
- Role-based outbound permission: a configurable allow-list of extensions

Adds a VoIP.ms SIP trunk on top of asterisk-digital-ocean: IP-authenticated
trunk (no password stored), NANP-only outbound dialplan, a global 3-call
concurrent cap via GROUP()/GROUP_COUNT(), and inbound routing to one
extension. Config lives in its own include files rather than being
appended directly to pjsip.conf/extensions.conf, since Easy Asterisk fully
regenerates both from its own internal state — the includes are patched
into the vendor's generator functions so they survive that regeneration.
Wires the new service into setup.sh's is_installed() and README's services
table, and updates docs/pstn-calling-voipms-plan.md to reflect what's now
implemented vs. still open (spend/volume alerting, live-account
verification).
- CrowdSec tab: per-ASN "Unwhitelist" (drop from the exempt filter, future
traffic evaluated normally) and "Unwhitelist + Ban" (also immediately
bans every IP CrowdSec has on record for that ASN, for accidental-
whitelist cases) buttons. set_asn_exempt now allows clearing the list
down to zero ASNs, needed to unwhitelist the last remaining entry.
- New sudoers permission (cscli decisions add --ip * --duration * --type
ban --reason *) scoped narrowly, list-form subprocess args only.
- Caddy/Authelia config factored into _secdash_configure_caddy() and a new
_secdash_remove_caddy_block() (whole-block delete-and-regenerate, not
in-place patching) so "update" mode can now offer to reconfigure it.
- Installer offers an independent HTTP Basic Auth layer in front of
Authelia (Caddy basicauth, generated via `caddy hash-password`) so a
future Authelia bug/misconfig alone isn't enough to expose a page that
can delete active security bans.
Currently-exempt ASNs with no active ban (e.g. T-Mobile once its bans
stop firing) had no carrier name to show, since the name lookup only
looked at cscli decisions list (active bans only). Add a
cscli alerts list-based fallback (includes expired/resolved alerts)
and merge it into the name lookup used by /api/asn-exempt.
Confirmed the real cscli decisions list -o json structure live rather
than guessing again: AS number/name and country live on each alert's
"source" object (source.as_number, source.as_name, source.cn), not on
the individual decision. Surfaces this as a "Network / Carrier" and
"Country" column in the bans table, adds a per-row "Exempt ASN" button
that appends straight to the Asterisk brute-force ASN exemption list,
and labels the exempt list's own entries with carrier names (pulled
from current ban data where available) instead of showing bare numbers.
Confirmed live: Caddy (in a container) reaches this via
host.docker.internal, a Docker bridge gateway IP, not localhost — a
loopback-only bind refuses that connection outright ("dial tcp
172.17.0.1:8092: connect: connection refused"), even though curl from
the host itself worked fine on 127.0.0.1. Bind to 0.0.0.0 and rely on
UFW for the actual access scoping instead, matching every other
host-network service in this repo (e.g. the Asterisk web admin, which
already binds this way successfully with the same
ufw_allow_from_caddy_net pattern).
Confirmed live: setup.sh's run_service() calls install_${name} with
no hyphen-to-underscore conversion, so a hyphenated service name needs
a literally-hyphenated function name (install_security-dashboard, not
install_security_dashboard) to be found at all — got this wrong on
first pass by following CLAUDE.md's own (incorrect) guidance, which
said to convert hyphens to underscores. Every other hyphenated service
in the repo (asterisk-digital-ocean, wolf-pair, mail-archiver,
drum-rhythm-game) already keeps hyphens literal; corrected CLAUDE.md
to match actual practice instead of the other way around.
New service, native on the host (not Docker) so it can call cscli and
read Asterisk's security log directly without bridging the
container/host boundary or exposing CrowdSec LAPI credentials to a
containerized frontend.
- Security Log tab: parses ~/docker/asterisk-digital-ocean/logs/full
for SIP auth failures (wrong password, unknown extension, etc.) with
timestamp/account/remote IP, classified by severity.
- CrowdSec tab: current bans via cscli, a delete/unban button per
entry, and ASN-exempt management for the Asterisk brute-force
scenarios (services/crowdsec.sh) without SSHing in.
- Link out to the existing Asterisk web admin (reads its domain from
asterisk-digital-ocean's own .env, doesn't hardcode or embed it).
Runs as a dedicated unprivileged system user (secdash), with sudo
scoped to exactly three commands via /etc/sudoers.d/security-dashboard
(cscli decisions delete --id <digits>, cscli decisions list -o json,
systemctl restart crowdsec) — validated with visudo -c. Listens on
127.0.0.1 only, reachable through Caddy, and refuses to proceed without
explicit confirmation if no Authelia (local or remote) is configured,
since this page can delete active security bans.
Stdlib-only Python (no framework), matching the RAM-conscious pattern
already used for Easy Asterisk's own web admin. All embedded code
(bash, Python, JS) syntax-checked; the generated sudoers rule

Confirmed live: unquoted integer literals in the ASN exclusion filter
(evt.Enriched.ASNNumber in [21928, 14593]) made CrowdSec fatal-crash-loop
at startup with "cannot use string as type int in array" — ASNNumber is
a string field internally despite printing as a bare number in cscli
output, same as IsoCode in the geo-allowlist scenario. Quote each ASN
as a string to match, exactly like the working geo-allowlist pattern.
Confirmed live: a phone roaming WiFi<->mobile on a CGNAT carrier
(Starlink, T-Mobile home internet) got banned by crowdsecurity/asterisk_bf,
either from its own re-registration burst or collaterally from another
customer sharing the same rotating public IP. Forks asterisk_bf and
asterisk_user_enum locally with an ASN exclusion added to their filter,
disabling the hub originals so events aren't double-processed. Scoped
narrowly to Asterisk auth-failure detection only — SSH, web scanning,
and the geo-allowlist scenario are all unaffected, so this doesn't
broadly exempt the carrier from every protection on the box.
Confirmed live: a legitimate SIP device on a CGNAT ISP (Starlink,
T-Mobile home internet) got collaterally banned by
crowdsecurity/asterisk_bf alongside actual bad actors sharing the same
carrier IP. The alert now includes the exact commands (with the banned
IP substituted in) instead of just naming the ban, so recovering from
this doesn't require remembering or looking up cscli syntax.
New "Add another protected domain to this instance" option on re-run,
via add_authelia_domain(): appends a session.cookies entry and an
access_control.rules entry (both YAML lists Authelia natively supports)
plus a Caddy auth.<domain> portal block for the new domain, all on the
same Authelia + Redis container instead of standing up a second full
stack. Each domain gets its own login/session, sharing one user
database — the right fit when a single (possibly upsized) droplet ends
up fronting more than one domain, without doubling the RAM cost of a
second Authelia+Redis instance. Documents both this and the
already-working separate-instance path in CLAUDE.md, with the
per-approach tradeoffs.
Misread the previous request as "add Russia to the allowed list" —
it meant the opposite: Russia should stay excluded, same as the other
high-risk/Eastern Europe entries already left out.
Excludes Bulgaria, Czechia, Hungary, Moldova, Poland, Romania, Slovakia,
and Ukraine per user request, while keeping the Balkans and Baltics
(several of which, e.g. Estonia, don't fit the same risk profile despite
the old Cold-War grouping). Russia added back to the allowed list per
explicit user request.
Opt-in prompt that bans any Caddy-fronted web request from outside an
editable North America + Europe country list, via a local CrowdSec
trigger scenario scoped to the existing "type: caddy" acquisition label.
Uses CrowdSec's bundled GeoLite2 enrichment data (already active with no
extra setup) rather than the firewall bouncer's separate MaxMind-key
country-CIDR feature, so no account signup is needed. SSH is untouched
so a bad edit can't lock out the session running the installer.
The generated auth.<domain> block's bare "reverse_proxy authelia:9091"
let Caddy recompute X-Forwarded-Host from its own incoming request
(always auth.<domain> itself) on every hop through it, overwriting
whatever a forward_auth caller elsewhere had already set for its own
domain. Confirmed live: a remote site's forward_auth check always
evaluated as if it were for the Authelia portal itself (bypass policy),
so 2FA silently never triggered for any domain going through it.
The previous fix used the {host} Caddy placeholder for X-Forwarded-Host,
but confirmed live it still evaluated to the upstream Authelia's own
hostname rather than the original site's — Caddy appears to rewrite the
outgoing request's Host to the upstream target before header_up
placeholders resolve for a scheme-qualified remote upstream, so {host}
echoed back the already-rewritten value. Since this site block only ever
serves one domain, hardcode it instead of depending on placeholder timing.
The remote-Authelia forward_auth block dialed a scheme-qualified upstream
(https://auth.example.com), which is a second Caddy hop. Caddy rewrites the
outgoing Host header to the upstream host for routing, and without an
explicit override X-Forwarded-Host picked up that rewritten value instead
of the original site's host. Authelia was evaluating every protected
domain as auth.example.com itself (bypass policy), so 2FA never triggered
for any domain behind the remote instance. Pin the forwarded headers to
the original request explicitly to fix it.
Both Caddy site block generators (the shared configure_caddy_for_service
helper, and asterisk-digital-ocean.sh's own inline template) wrote
reverse_proxy before the forward_auth/import authelia block. Caddy
doesn't reorder repeats of the same directive within a block — forward_auth
and reverse_proxy are the same directive family internally, so they run in
the order written. With reverse_proxy first, it handled and terminated
every request immediately; the auth check written after it never ran at
all. Full bypass on every domain using either generator with Authelia
protection, regardless of how correct the Authelia access_control rules
themselves were — confirmed live against a config that was otherwise
completely correct (default_policy: deny, explicit wildcard rule covering
the affected domain).
Affects every service that's ever passed `import authelia` or a
forward_auth block through configure_caddy_for_service (asterisk.sh,
wolf-pair.sh, and any future caller), plus asterisk-digital-ocean.sh's
own site block.
Moved the auth block before reverse_proxy in both generators.

wolf-pair has no login of its own — Authelia via Caddy is the only
protection option offered for it — but UFW opened its port to the
whole internet unconditionally, before the Caddy/Authelia prompt even
ran. Same gap just fixed for the Asterisk web admin: reachable
straight over the bare port regardless of Authelia.
Reordered so the Caddy decision happens first, and scope the port to
caddy_net's subnet via ufw_allow_from_caddy_net() instead of leaving
it open to 0.0.0.0/0 when Caddy fronts it locally. Also enables UFW
via ensure_ufw_enabled() like the Asterisk services.

Confirmed live: a bare `ufw delete allow <port>` closes it on every
interface, including the caddy_net bridge — Caddy's own request to
host.docker.internal:PORT is ordinary INPUT-chain traffic as far as
UFW is concerned, not something that bypasses it just because the
source is a local container. Closing the port outright silently took
Caddy's reverse-proxy path down with it.
Added ufw_allow_from_caddy_net() to scope the port to caddy_net's own
subnet instead of leaving it fully closed — reachable from Caddy,
still closed to the public internet. Wired into both
asterisk-digital-ocean.sh and asterisk.sh in place of the plain
delete.

Mirrors the fixes just made in asterisk-digital-ocean.sh:
- Reordered so the Caddy reverse-proxy decision happens before the
UFW rules are built, using the new CADDY_SERVICE_CONFIGURED/
CADDY_SERVICE_MODE signal from configure_caddy_for_service() to
skip opening the web admin port on the LAN when a local Caddy is
already fronting it (still opens it for a remote Caddy machine,
which needs LAN access to reach this host directly).
- Calls the new ensure_ufw_enabled() so UFW actually enforces the
rules this script adds, instead of leaving them queued but inert.

UFW and the DO Cloud Firewall both opened the web admin port to
0.0.0.0/0 unconditionally, even when Caddy+Authelia was configured to
protect it on the actual domain. Caddy reaches the container over the
host's internal network (host.docker.internal), not the public
internet, so that direct port was pure attack surface: anyone could
hit http://<droplet-ip>:<port>/clients directly, fully bypassing
Authelia and the built-in web admin auth (which gets disabled
whenever Authelia is handling it instead).
Reordered the install flow so the Caddy reverse-proxy decision is
made before the firewall rules are built, and only open the web
admin port publicly when there's no local Caddy actually fronting
it (no domain, Caddy not installed, proxy declined, or a remote
Caddy machine that needs to reach it over the public IP instead).

Renamed services/asterisk-do.sh -> services/asterisk-digital-ocean.sh
(register_service name, install function, install dir, and all prose/
comments) so the whiptail menu shows a clearer, more discoverable name.
Updated the functional cross-references that depend on the old name:
crowdsec.sh's SIP-log auto-detection path and acquisition filename,
caddy.sh's host.docker.internal comment, and the CLAUDE.md/README.md
docs (services table, directory listing, network-wiring example).
Container names, the Docker Compose project name, and the internal
_asterisk_do_* helper function identifiers are left unchanged since
they aren't user-facing and renaming them would add risk for no
benefit.

Same pattern already used for NetBird: a simple prompt (default yes,
since these are the two explicitly called out as recommended) right
after the mandatory package/Docker/SSH setup, before the whiptail
menu. Both stay fully optional and available later from the menu
either way — this just surfaces them earlier as a nudge, matching
how most other services in this repo end up wanting a reverse proxy
and something watching for brute-force/scan traffic.
asterisk-do previously offered to auto-install base, Caddy, CrowdSec,
and a numbered extras menu (authelia/ntfy/watchtower/wg-easy/netbird/
backup) on top of its own setup, layering a second install flow on
top of the whiptail menu setup.sh already provides. Strips all of
that back out — asterisk-do now only installs Asterisk + coturn, same
scope as any other service. Caddy/Authelia integration (reverse
proxy, cert sync, SSO) is kept, since it only activates when those
are already installed — no auto-install behind it. CrowdSec SIP
protection still wires up automatically via crowdsec.sh's own
asterisk-do detection, regardless of which one installs first.
Also fixes a real regression from ensure_caddy_network (added
earlier): it created caddy_net via a bare `docker network create`,
which doesn't carry Compose's ownership labels, so Caddy's own
non-external network declaration conflicted with it and failed to
start ("network exists but was not created by compose"). Caddy's
compose file now declares caddy_net as external: true like every
other service, since ensure_caddy_network is the single creator for
all of them, Caddy included.
43 services declare caddy_net as "external: true" in their compose
file, meaning they require it to already exist — but only Caddy's own
compose file actually creates it (authelia.sh was the sole exception,
with its own inline check-and-create). Installing any of the other 42
before Caddy fails outright with "network caddy_net declared as
external, but could not be found."
Adds ensure_caddy_network to lib/common.sh, called from require_docker
(which every install_* function already calls first), so the network
exists regardless of install order without touching each service file.
Removes authelia.sh's now-redundant duplicate of the same check.
Also documents in CLAUDE.md that network_mode: host services (asterisk/
asterisk-do) need host.docker.internal, not localhost, when Caddy
reverse-proxies to them — the fix from the previous commit.
Caddy runs in its own container on the caddy_net bridge network, so
"localhost" in a Caddyfile site block resolves to Caddy's own
container — never the host, and never a sibling container. That
broke every reverse proxy pointed at a network_mode: host service
(confirmed live with asterisk-do's web admin): once nothing else
(like a forward_auth redirect) intercepted the request first, Caddy
couldn't actually reach the upstream.
- services/caddy.sh: add extra_hosts so host.docker.internal resolves
inside the Caddy container (Linux Docker needs this explicitly —
it's automatic only on Docker Desktop).
- lib/common.sh's configure_caddy_for_service: bare-port upstreams
(its documented "host-network service" case) now target
host.docker.internal instead of localhost.
- services/asterisk-do.sh: its self-contained Caddy block (doesn't go
through configure_caddy_for_service) gets the same fix for local
Caddy, and now correctly targets the droplet's public IP instead of
localhost for the remote-Caddy snippet case, which had the same bug.
services/asterisk.sh needs no direct change — it already goes through
configure_caddy_for_service, so it inherits the fix.
Replaces the y/n "update in place?" prompt in asterisk.sh/asterisk-do.sh
with an explicit r/f/c choice — (r)einstall in place, (f)ull install,
(c)ancel — defaulting to cancel on a bare Enter (or Ctrl-D) instead of
falling through to a destructive full reinstall.
Adds prompt_reinstall_mode to lib/common.sh (plus matching standalone
stubs in both asterisk scripts for when they run without the full repo)
and documents the convention in CLAUDE.md: any service with a persistent
install directory should offer this choice on rerun instead of re-asking
every prompt just to pick up a script fix.
Re-running either installer on an existing install used to re-ask
every prompt (domain, extras, firewall, Authelia) just to pick up a
script fix like the exports mount. Both now detect an existing
docker-compose.yml + .env and offer to update in place instead: only
vendor files and docker-compose.yml are refreshed and the stack is
rebuilt, leaving .env, firewall rules, and Caddy/Authelia config
untouched.
The vendor-copy and docker-compose.yml generation blocks (previously
inline and duplicated between what would have been two near-identical
code paths) are factored into per-file helper functions
(_asterisk_do_refresh_vendor_files/_asterisk_do_write_compose and
_asterisk_refresh_vendor_files/_asterisk_write_compose) so fresh
installs and updates share one copy of the logic instead of drifting
apart — the same problem that caused the /root export path and the
vpn-diagnostics.sh COPY bug to slip through unevenly between the two
services in the first place. Names are per-file since setup.sh sources
every services/*.sh into one process.
The vendor easy-asterisk script hardcodes /root for both export output
and its import file listing, but nothing was mounted there — exports
were being written to the container's ephemeral filesystem and lost on
recreate. Bind-mount ./exports to /root in both asterisk.sh and
asterisk-do.sh so exports/imports land under ~/docker/<service>/exports
on the host.
