Add inbound concurrency cap, bump defaults to 10/10, make caps live-editable
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. |

PSTN trunk: 3-tier live permissions + Security Dashboard web UI + dual target
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). |

Rework PSTN trunk: role-based permissions, ring-groups, ntfy spend alerts
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"). |
