Claude e1c3203d88 Add sms-inbound: verification codes from a VoIP DID to ntfy push
New service for one narrow job — getting SMS verification codes sent to a
VoIP number onto a phone with no SIM. Deliberately not a texting app: no
outbound path (Anveo Direct has none; that needs an Anveo Retail account, and
a free texting app covers sending), and messages arrive as push notifications
rather than being routed into Asterisk as SIP MESSAGE, since a code you read
and type is better served by a notification than a softphone chat thread.

Two modes, both driven entirely from the provider's "forward SMS to URL" box:

- direct — the provider calls ntfy itself; nothing installed here. ntfy
  accepts GET publishing at /{topic}/(publish|send|trigger) with message and
  title as query params, and auth via ?auth= holding base64url (unpadded) of
  the literal "Bearer <token>" — confirmed against ntfy's server.go and
  server_auth.go rather than its docs.
- relay — a stdlib systemd service, Caddy-fronted on its own domain with no
  Authelia (the provider can't log in; a random 32-char token in the path is
  the secret). Buys two things direct mode can't have: an unescaped "&" in a
  message body survives intact, because the relay takes everything after the
  last message= verbatim instead of parse_qs — which is why the generated URL
  always puts the message placeholder last — and no ntfy credentials sit in a
  third party's web portal.

Verification codes are bearer credentials, so: a 24-char random topic name
(the repo's ntfy defaults to auth-default-access: read-write, making the topic
name the read credential), constant-time token compare, a 60/min rate limit,
and the relay logs sender/recipient/length but never the message body.

The Anveo guide gains a section covering the two things that actually decide
whether codes arrive: short-code support (Anveo has it, unusually — VoIP.ms
does not except for Google) and Anveo's carrier-sourced *mobile* DIDs, which
are classified as mobile in the lookups that reject VoIP numbers at signup.
Also documents MMS and group texts being out of reach, and why the native
Messages app never sees any of this.

Verified against a stub ntfy: plain OTP, encoded "&", unencoded "&", "+" as
space, wrong token (404), missing message (400) and the rate limit (57x204
then 429) all behave; both installer modes were run end to end in a sandbox
and their generated URLs, settings files and READMEs checked.

# Anveo Direct + Easy Asterisk — confirmed working setup guide
This is the exact sequence that got a real Anveo Direct DID working end to
end (both outbound and inbound) with `asterisk.sh` + `pstn-trunk.sh`,
confirmed live on a real droplet.
**Steps 1, 3 and 4 are one-time account setup** — the outbound Service
Trunk (step 3) and the inbound SIP Trunk (step 4) each cover every DID on
the account, no matter how many you add. **Only steps 2, 4.5, 6 and 7
repeat per number**: order the DID, point it at the existing inbound trunk
(skippable entirely if you set the account default in step 4.6), assign it
in the dashboard, and test.
## 0. Prerequisites
- `asterisk.sh` already installed and running (droplet or home/LAN — the
installer detects which), with at least one extension configured.
- This box's public IP address (`curl -4 ifconfig.me`).
## 1. Anveo Direct account (one-time)
1. Create an account at `https://www.anveo.com/account.asp?account_type=direct`
— this is what makes it a **Direct** account (trunk/DID product), not
the hosted-PBX product.
2. Fund the account balance directly (not a subscription plan). Bank
transfers can take several hours to clear.
3. **Known account-level caps as of this writing**, both separate from
anything this installer enforces:
- **Trial account limits**: 2 concurrent outbound calls (CPS: 2),
$2/30-day spend limit, $2 minimum balance — shown on the Outbound
Trunks page under "Account Limits." A "request higher limits" link
sits next to the CallerID Policies section for asking Anveo to lift
these once funded.
- **Phone Numbers cap**: "You can manage up to 2 phone numbers. Please
contact customer support to increase the limit" — a **separate** cap
from the concurrent-call limit above, shown on the Phone Numbers
summary page. Anveo indicated (not independently confirmed) that
removing this requires providing a tax ID (EIN for a business, SSN
for an individual) — decide for yourself whether that trade-off is
worth it before planning on more than 2 DIDs.
4. CallerID policy: USA/Canada/international destinations all require
CallerID **from a verified/Anveo-owned number** — any DID ordered
through Anveo satisfies this automatically.
## 2. Order a DID
1. Go to the DID ordering tool ("Phone Numbers around the World" /
similar), pick a number, and select the **Per Minute** rate plan — not
Prime.
- **Per Minute**: $0.004/min incoming, 10 dedicated incoming channels
bundled in, no separate trunk product needed for inbound.
- **Prime**: free incoming, but requires a separately-purchased "Anveo
Trunk" (a *different* product — flat monthly fee, $6.50$17/mo by
zone, confirmed via the "Anveo Direct Trunk Price List" page). Per
Minute avoids this fee entirely, which is why it's the one to use.
2. Confirm: $0.25 one-time setup, $0.15/month recurring (billed the 15th),
3-month minimum term, pre-paid from account balance.
## 3. Create the Outbound Service (Call Termination) Trunk
This only needs to be done **once** — the same trunk carries outbound
calls for every DID/extension. Skip this step for DIDs 2+.
1. Outbound Trunks → **Add a new Call Termination Trunk**.
2. Fill in:
- **Title**: any label (e.g. `asterisk-do`)
- **Dialing Prefix**: leave **blank** — confirmed not required (no red
"required" asterisk on this field, unlike Authorized IP Addresses and
Call Routing Method). The dialplan here dials the bare number, no
prefix.
- **Authorized IP Addresses**: this box's public IP, one per line. This
is the IP-authentication Anveo uses instead of a SIP password.
- **Rate Cap**: optional safety ceiling — e.g. `Yes, $1/min` filters out
any route pricier than that. Domestic US termination runs far below
this, so it doesn't interfere with normal calls, just blocks getting
routed onto an absurdly expensive carrier by accident.
- **Concurrent Calls Limit**: whatever you want as an Anveo-side cap
(e.g. `Yes, 6`) — note the account's Trial "Outbound Channels: 2"
limit (see step 1) overrides this until lifted; whichever number is
lower wins.
- **Call Routing Method**: leave the default **Custom Least Cost
Routing Model** and all of its sub-fields (All Prime Routes / cost
lowest-to-highest / 5 routes / cost-ordered failover / 10 sec
timeout) exactly as shown — sensible defaults, nothing to tune here.
3. Save.
### Finding the real outbound rate
The trunk's LCR pulls from **"All Prime Routes"** by default — meaning
your real per-minute cost is whatever's in the **Anveo Direct Prime** rate
card (Outbound Services/Call Termination page → "Download rates here"
under the **Prime** column, not Value/Standard/All). Confirmed from that
CSV: standard US-to-US domestic is a flat **`$0.00388/min`**, billed
per-second (not rounded to the minute) — this is the generic `USA.`
catch-all entry (prefix `1`); a few specific area codes have their own
slightly different override rates, and Virgin Islands is billed
separately/higher (~$0.02/min) despite looking like a normal US number.
## 4. Create the SIP Trunk (inbound forwarding) — ONE covers every DID
Anveo has **two unrelated "trunk" concepts** — don't confuse them:
- The **Outbound Service Trunk** from step 3 handles calls *out*.
- A separate **"SIP Trunk"** object (Account Options → wherever inbound
routing objects live) handles calls *in* — this is what actually
populates a DID's "Destination SIP Trunk" dropdown.
**You only need ONE of these for the whole account**, no matter how many
DIDs you have. The `$[E164]$` placeholder in step 2 is what makes it
reusable — Anveo substitutes each DID's own number at call time, so the
same trunk object forwards `15551111111@IP:5060` for one DID and
`15552222222@IP:5060` for another. The Asterisk side matches whatever
arrives (`_X.` in `[from-pstn-trunk]`) and looks it up in
`pstn-personal-dids.conf` to decide who rings. Creating one per DID is
possible but pointless unless different DIDs need to forward to genuinely
different destinations.
Create it once (steps 14), then per DID only step 5 applies — or set the
account default in step 6 and skip even that:
1. **Trunk Name**: any label (e.g. `asterisk-do-inbound`).
2. **Primary**: type **SIP URI**, value:
```
$[E164]$@<this box's public IP>:5060
```
(port 5060 — Easy Asterisk's default SIP port, confirmed from its own
vendor source `DEFAULT_SIP_PORT="5060"`). The `$[E164]$` placeholder is
replaced by Anveo with the DID's own number, digits only, country code
included, no `+` — e.g. DID `+15551234567` becomes `15551234567@IP:5060`
in the actual INVITE Anveo sends.
3. **Failover**: leave blank.
4. Save.
5. **Per DID**: go to that DID's **Call Options** tab → set **Destination
SIP Trunk** to this SIP Trunk object (not the Outbound Service Trunk)
→ Save.
6. **Recommended if you have more than one or two DIDs**: Account
Options → Service Defaults → set **Default Destination Trunk** to this
SIP Trunk. New DIDs then auto-route here and step 5 becomes unnecessary
entirely.
## 5. Configure the droplet
```
sudo ./setup.sh pstn-trunk
```
- Existing install → choose **update** (`r`) if you're just changing the
DID/server, or the CLI will walk fresh prompts if none exists yet.
- Provider quick-pick: **1) Anveo Direct** — pre-fills `sbc.anveo.com` and
Anveo's 4 published signaling IPs (only one of which the hostname
itself resolves to at any given moment; the others are entered as
"additional known source IPs" so inbound is recognized regardless of
which one a call actually arrives from).
- **DID**: 10 digits, no leading `1` (e.g. `5551234567`).
- **Outbound per-minute rate**: `0.00388` (see step 3's rate-lookup note)
— pre-filled automatically when Anveo Direct is the selected provider.
- Concurrent-call caps, ring-group extensions, ntfy topic, spend-cap
kill-switch thresholds: set to taste (all live-editable later without
reinstalling).
- Who can call/be called (permission tiers, approved numbers), internal
SIP messaging, and personal-number assignment are **not** prompted here
— set them all in the Security Dashboard's **PSTN Trunk** tab instead
(install it first if you haven't: `sudo ./setup.sh security-dashboard`).
Every extension starts at `internal` (no PSTN access) until granted
there.
## 6. Grant permissions and (optionally) a personal number
In the Security Dashboard's PSTN Trunk tab:
1. Set the tier for each extension that should get PSTN access (`full` or
`restricted` — `restricted` also needs at least one approved number).
2. **Personal numbers** card: assign this DID to a specific extension if
you want inbound calls to it to ring *only* that extension (instead of
the whole shared ring-group) and its outbound Caller-ID to show this
DID instead of the shared trunk DID. Enter the DID as **10 digits, no
leading 1** (matches the same convention as the trunk DID above) —
the dashboard's own input validates against exactly that format.
You can assign the DID to a **group** instead of a single extension —
pick `Group: <name>` in the owner dropdown (create the group first
under Groups if it doesn't exist yet). Every current member whose own
tier/approved-numbers authorize the caller rings, checked fresh on
every call, so membership changes apply immediately with no reinstall.
A group has no single extension to hang an outbound Caller-ID override
on, so the Caller-ID-override part above only applies to
single-extension assignments.
## 7. Test
- **Outbound**: from a full/restricted-tier extension in Sipnetic, dial
`1` + area code + number (11 digits total — the dialplan matches the
full NANP pattern, not a bare 10-digit number without the leading `1`).
- **Inbound**: from any outside phone, dial the DID's real number. If a
personal number was assigned, only that extension should ring; if not,
the whole configured ring-group rings simultaneously until someone
answers or 20 seconds pass.
- Watch the live console while testing either direction:
```
docker exec -it easy-asterisk asterisk -rvvv
# on a droplet set up before the two Asterisk services were merged, the
# container is named easy-asterisk-do instead
```
## 8. SMS — receiving verification codes
Voice and SMS are separate features on an Anveo DID and are configured in
different places. This section covers **receiving** only; see "What about
sending?" below for why.
### Pick the right kind of number first
Anveo sells two classes of US DID, and for verification codes the difference
matters more than anything else in this section:
- **Geographic (default)** — the cheap ones this guide orders in step 2
($0.25 setup, $0.15/month). Industry lookups classify these as VoIP.
- **Mobile** — a separate pool sourced from wireless carriers, available
across roughly 20 major US city area codes (released on Anveo Retail first,
then Direct). These are classified as *mobile* in the same databases that
services query when they decide whether to accept your number. Priced above
the geographic ones — check the DID ordering tool for the current rate.
Plenty of services (Google, WhatsApp, Microsoft, many banks) reject a number
that looks like VoIP at signup, before any message is ever sent. **If codes
are the reason you're buying the number, order a mobile one** — no amount of
correct SMS routing fixes a signup form that refuses the number outright.
### Short codes
Most verification codes come from short codes (262966, 32665, ...), and most
VoIP providers don't deliver them at all — VoIP.ms, for instance, doesn't
except for Google, and users there report a large fraction of 2FA codes never
arriving. Anveo is unusual in supporting short-code SMS to its DIDs, which is
the main reason it's worth using for this.
Not every number in the pool has it enabled, so confirm on your specific DID
(or ask support to turn it on) rather than assuming.
### Wire it up
Run the installer and follow what it prints:
```bash
sudo ./setup.sh sms-inbound
```
It generates a long random ntfy topic, then offers two ways for Anveo to
reach it:
- **Relay (recommended)** — a small systemd service on the droplet receives
Anveo's request and republishes to ntfy properly. Two concrete wins: a
message body containing `&` survives intact (Anveo interpolates the text
into the query string unescaped, so an unencoded `&` otherwise truncates
the message), and your ntfy credentials never get stored in Anveo's portal.
- **Direct** — Anveo calls ntfy itself; nothing runs on the droplet. Simpler,
but the URL you paste into Anveo carries your ntfy token, and the `&` case
loses the tail of the message.
Then in the Anveo portal: **Phone Numbers → the DID → SMS tab**, set the
destination to **URL**, and paste the string the installer printed. Keep the
`$[message]$` placeholder **last** — that's what makes the unescaped-`&` case
recoverable.
Send a text to the number from another phone; the notification should arrive
within seconds. `journalctl -u sms-inbound -f` shows sender, recipient and
message length (never the body — these are one-time passcodes and the journal
has a wider audience than the notification does).
### What about sending?
Not covered, on purpose. Outbound SMS isn't available on Anveo Direct — Anveo
support directs users to an Anveo **Retail** account for it, which is a
second account to fund and manage. Any of the free texting apps covers
sending without involving this box.
### MMS and group texts
Don't plan on either. No VoIP provider delivers MMS over SIP, and MMS to a
VoIP DID generally drops or arrives as a media link through a separate API.
US group texts are MMS, so a SIM-less phone on this number will silently miss
them.
### The native Messages app never sees these
Android's Messages app reads the telephony SMS provider, which only the
cellular radio (or whichever app holds the default-SMS-app role) writes to;
iOS lets nothing write to Messages at all. Codes arrive as ntfy push
notifications instead — which, for a passcode you're about to read and type,
is the more useful place anyway.
## Bugs hit and fixed along the way (informational — already fixed)
These were all real, confirmed-live bugs in earlier versions of this
installer, not configuration mistakes — listed here for context on what
"just works" now that didn't before:
- **NANP dial pattern was one digit short** (`_1NXXNXXXXX` / `_NXXNXXXXX`,
10/9 characters instead of the correct 11/10) — Asterisk's exact-length
pattern matching never matched a real number at all.
- **`${CHANNEL(peername)}`** isn't a valid channel-function item on this
Asterisk build — broke the caller-extension lookup used for every
permission check.
- **`${EXTEN}` corruption after `Goto` to a named extension** — every
`Goto(somelabel,1)` to a *different* extension (not a same-extension
priority label) resets `${EXTEN}` to that label's own name, silently
breaking the approved-numbers check, the international country check,
and the final `Dial()` itself. Fixed by capturing the real dialed
number into its own variable before any such jump.
- **Duplicate ring-group extensions** (the same extension listed twice in
`RING_EXTS`) generated duplicate dialplan priority labels, causing an
infinite loop that never reached the ring step at all. Now deduped
automatically.
- **Personal-DID lookup format mismatch** — DIDs are stored 10-digit, but
Anveo delivers the called number as 11-digit E.164 in `${EXTEN}`; the
lookup now normalizes to 10 digits first.
- **Easy Asterisk only regenerates `pjsip.conf`/`extensions.conf` if they
don't already exist** — a box that already has devices configured (the
normal case) never picks up a vendor-script `#include` patch on a plain
restart. Both the PSTN trunk and internal-messaging installers now also
patch the live config files directly, not just the generator source.
- **A stale/malformed `.pstn-trunk.env`** could crash the entire installer
under `setup.sh`'s `set -u` on `source`. Now guarded and falls back to
safe defaults, erroring clearly only if genuinely required fields are
missing.
- **The inbound `[from-pstn-trunk]` context never loaded at all** — it used
to share one `#include`'d file with the outbound dialplan, where the file
continued `[intercom]` first and only declared `[from-pstn-trunk]`
partway through. Asterisk silently failed to load the *entire* file
(outbound patterns included) with no error anywhere, so every inbound
call got "extension not found in context 'from-pstn-trunk'" and an
immediate SIP rejection. Inbound now lives in its own file that starts
with its context header, matching the structure of the messaging
dialplan that always loaded correctly.
- **Every inbound call's Caller-ID arrived as the DID itself**, not the
real caller — the trunk endpoint pinned a static `callerid=<DID>` and
didn't set `trust_id_inbound`, so Asterisk ignored the identity Anveo
actually sends and fell back to that default. Every restricted-tier
`allowed_numbers` check was therefore unwinnable regardless of config.
Fixed by dropping the static default (redundant — the outbound dialplan
sets `CALLERID(num)` on the channel itself) and adding
`trust_id_inbound=yes`.
- **A leading `+` broke whitelist matching** — once the fix above started
surfacing real caller identity, Anveo delivers it `+E.164` style
(`+15551234567`). The normalizer only added a leading `1` to 10-digit
values and never stripped the `+`, so a 12-character value could never
match an 11-digit, digits-only `allowed_numbers` entry no matter how
correctly the number was whitelisted. The `+` is now stripped in the
dialplan, the group-ring script, and the dashboard's admin-input side
(so pasting a number straight from a call log works too).
- **Bare `Hangup()` on inbound denials** instead of `Busy(15)` — three
inbound denial paths didn't produce a proper "486 Busy Here", making a
correct permission denial sound like a generic call failure and
disguising config mismatches as dialplan bugs.
## Dashboard changes may need "Commit Changes"
Confirmed live: edits made in the Security Dashboard's PSTN Trunk tab
(permission tiers, groups, personal-DID owners, limits) are written to disk
immediately, but `AST_CONFIG()` in the dialplan has been observed still
returning the *old* value until the Asterisk container is fully restarted —
a `dialplan reload` / `module reload` is not enough. This contradicts the
"reads fresh on every call, no restart needed" design premise these files
otherwise rely on; root cause not established.
The PSTN Trunk tab has a **Commit Changes (Restart Asterisk)** button for
this, which appears after any save on that tab and warns if you navigate
away with changes uncommitted. Existing calls are unaffected by the
restart. If a change doesn't seem to be taking effect on a test call, press
it before assuming the config itself is wrong.
## Still open
- Nothing blocking. The two items previously listed here are both resolved:
the 2-phone-number account cap no longer applies (additional DIDs have
since been obtained), and the interactive CLI walkthrough was built —
see `_pstn_anveo_walkthrough` in `services/pstn-trunk.sh`, reachable from
the provider quick-pick when you choose Anveo Direct.
