- Investigated the real callcenter_config command surface via
'help callcenter_config' on the running FreeSWITCH before writing any
code: queues only have load/unload/reload (static XML + reload, no
'queue add' exists), while agents and tiers are fully dynamic via ESL
commands (agent add, tier add) -- no file involved. This shapes the next
phase (Agents/Tiers) differently from this one.
- queues table (tenant-scoped, RLS): strategy, moh/announce, wait times,
tier rules, discard/abandoned handling, skip-agents-with-external-calls,
recording_enabled
- packages/telephony: buildQueueXml()
- infrastructure/freeswitch: our own callcenter.conf.xml override (empties
the vanilla static agents/tiers -- those become fully dynamic in the next
phase) that includes callcenter_queues.conf.d/*.xml via X-PRE-PROCESS,
same pattern as the Sofia gateway directory
- apps/api/src/queues: CRUD (POST/GET/GET:id/DELETE) using the queues.view/
.manage permissions already in the seed
- b2bcall-fs-config (queue-sync.ts): one XML file per queue on a shared
volume, synced via Redis pub/sub (b2bcall:queues:sync) on create/delete
and once at boot -- same shape as trunk-sync.ts
- confirmed manually against the real FreeSWITCH, before coding the sync
logic: 'queue load <name>' fails ('Invalid Queue not found!') for a file
added after boot -- needs 'reloadxml' first to repopulate the in-memory
XML tree from disk; after that, 'queue reload <name>' alone handles both
create and update, no need to distinguish load vs reload
- verified end-to-end: created a queue (ROUND_ROBIN, maxWaitTime=120,
discardAbandonedAfter=90), 'callcenter_config queue list' showed the
correct values on the FreeSWITCH side; deleted it, list went back empty
docs/QUEUES.md
- dialplan_extensions table (tenant-scoped, RLS): structured editor per
agente.md secao 43 -- context, condition field/expr, actions/anti-actions
(JSON), continue, order, enabled. One condition per extension (deliberate
simplification vs raw FreeSWITCH's multi-condition extensions).
- dialplan_versions table (tenant-scoped, RLS): generate/validate/version/
activate flow (secao 44). Reactivating an older version IS the rollback
mechanism -- no separate endpoint needed.
- apps/api/src/dialplan: extensions CRUD + versions/generate (builds XML,
validates well-formedness with fast-xml-parser, saves as DRAFT) +
versions/:id/activate (atomically flips ACTIVE, supersedes the previous
one). Reused freeswitch.view/.configure permissions rather than inventing
new ones not in the agente.md permission list.
- packages/telephony: buildDialplanXml() plus ALLOWED_DIALPLAN_APPLICATIONS,
an explicit allowlist (answer/bridge/playback/hangup/set/export/... --
deliberately no system/exec/socket) guarding against a tenant configuring
a dialplan action that runs arbitrary commands on the FreeSWITCH host
(agente.md secao 180)
- b2bcall-fs-config resolves dialplan dynamically per call (unlike Trunks'
file+rescan approach -- dialplan is fetched fresh via mod_xml_curl on
every call anyway) by tenant id from the variable_b2bcall_tenant_id
channel variable already injected at directory resolution, then serving
whichever DialplanVersion is ACTIVE for that context
- verified end-to-end: created a rule for destination_number 7000, generated
and activated v1, originated a call that actually routed through the
dialplan (not bypassing it via &app()) -- CALL_CREATED -> CALL_ANSWERED ->
CALL_ENDED with the correct tenantId throughout. Created and activated a
v2, then rolled back to v1 by reactivating it; status transitions
(ACTIVE/SUPERSEDED) all confirmed via the API.
CRITICAL FINDING, fixed in this same phase: deliberately testing that the
application allowlist rejects 'system' got back 201 instead of 400 --
NestJS's ValidationPipe had been silently inert across all of apps/api's
@Body() DTOs since the API was first created. Root cause: running via
(esbuild) instead of a real build -- esbuild doesn't always
resolve cross-file parameter types for design:paramtypes metadata, and Nest
skips validation without any error when it can't determine the DTO class.
Fixed by always building with tsc before running (tsc && tsx dist/main.js
-- still via tsx because internal workspace packages aren't built to JS
yet). Re-verified with two deliberate bad-input tests post-fix, both
correctly rejected with 400. A stray malicious test row (dialplan action
'system') created while the bug was live was deleted; it was never baked
into an activated version, so nothing could have executed it.

docs/DIALPLAN.md, docs/VALIDATION_PIPE_BUG.md, docs/EXTENSIONS.md updated
- trunks table (tenant-scoped, RLS): host/proxy/realm, register,
username/password_enc (AES-256-GCM), dtmf_mode, ping, transport, and a
status/status_updated_at pair meant to be driven by FreeSWITCH events
- apps/api/src/trunks: CRUD (POST/GET/GET:id/DELETE), same RBAC/tenant
pattern as Extensions, password never exposed in any GET
- packages/telephony: buildGatewayXml() generates a Sofia gateway XML file
- b2bcall-fs-config now writes sip_profiles/external/<trunk_id>.xml (shared
Docker volume with FreeSWITCH -- the vanilla external profile already
includes external/*.xml) and runs 'sofia profile external rescan' over
ESL; syncs on boot and on demand via Redis pub/sub
(b2bcall:trunks:sync), since apps/api runs on the host and fs-config has
no port published to reach directly
- added FreeSwitchTelephonyProvider.waitUntilConnected() to fix a startup
race: the first sync ran before the ESL connection had settled, logging
a harmless but noisy error
- verified end-to-end with a fake host: create trunk -> gateway file
written -> FreeSWITCH shows the real gateway (FAIL_WAIT, expected) ->
delete -> file removed (cleanup also correctly swept the stale
'example.com' gateway that had been copied into the volume from the
vanilla image)
- apps/freeswitch-events/src/trunk-status.ts: written to update Trunk.status
from sofia::gateway_state events, using the same normalizeEslEvent path
already proven for CHANNEL_* events
- KNOWN GAP, documented rather than glossed over: monitored fs-events for
~90s while the gateway visibly transitioned states in FreeSWITCH
(FAIL_WAIT/DOWN) and no sofia::gateway_state event was observed arriving.
CUSTOM/sofia::* events have not actually been proven working end-to-end
in this session -- only CHANNEL_* events have been. Needs verification
against a real SIP target before the status auto-update can be trusted
in production. See docs/TRUNKS.md and TODO.md.
- docs/TRUNKS.md
- extensions table (tenant-scoped, RLS): number, sip_password_enc
(AES-256-GCM via packages/shared/src/crypto.ts), caller_id, context,
sofia_profile, codecs, max_registrations
- apps/api/src/extensions: CRUD (POST/GET/GET:id/DELETE), protected by a
new generic PermissionGuard (@RequirePermission decorator), tenant
resolved only from the JWT (never trusted from the client)
- SIP password is returned in plaintext only once, in the create response;
toPublicExtension() explicitly destructures the encrypted field out
(not a spread) so it can't leak by accident
- b2bcall-fs-config now resolves real directory data: Tenant.telephonyDomain
-> Extension.number, decrypts the password, builds proper directory XML
including a dial-string param (missing it caused originate to fail with
MANDATORY_IE_MISSING instead of the expected USER_NOT_REGISTERED)
- pinned FreeSWITCH's 357737{domain} to a stable value (b2bcall.local) via a
vars.xml patch in the Dockerfile -- it previously used the container's
dynamic IP, which could never match a stored telephony_domain
- added HTTP Basic auth between FreeSWITCH and fs-config
(gateway-credentials, timingSafeEqual comparison) now that the service
returns real secret data, closing the gap flagged as pending in the XML
Curl phase instead of leaving it open
- found and fixed: PermissionGuard's constructor-injected Reflector came
back undefined at runtime under tsx/esbuild (unreliable cross-file
decorator metadata emission) -- fixed with an explicit @Inject(Reflector);
worth watching for in future guards/services run via tsx
- verified end-to-end: create extension -> originate user/<ext> reports
USER_NOT_REGISTERED (found, not registered) -> delete -> back to
SUBSCRIBER_ABSENT (not found); password never reappears in any GET;
unauthenticated fs-config requests get 401
- docs/EXTENSIONS.md
- packages/telephony: TelephonyProvider interface (agente.md secao 25) and
FreeSwitchTelephonyProvider implementation over the 'esl' library
(actively maintained, TypeScript-native, built-in reconnect-with-backoff
satisfying secao 195); normalizeEslEvent() translates raw ESL events into
the internal vocabulary (secao 24)
- apps/freeswitch-events (b2bcall-fs-events): permanent ESL connection,
resubscribes on every reconnect, publishes normalized events to the
'b2bcall:events' Redis pub/sub channel; containerized (Dockerfile +
docker-compose service) since its whole job is reaching the freeswitch
container by internal hostname
- packages/shared: reusable createLogger() (structured JSON per secao 189),
fixed a BigInt serialization crash surfaced by the esl library's error
stats
- found and fixed a real FreeSWITCH 1.11 default: without an explicit
apply-inbound-acl, mod_event_socket silently rejects any non-loopback
connection ('Access Denied, go away.') even with the correct password —
added a dedicated ACL (loopback + the Docker Compose network range, never
0.0.0.0/0) in infrastructure/freeswitch/overrides/autoload_configs/
- verified end-to-end with a local loopback test call: CALL_CREATED ->
CALL_ANSWERED -> CALL_ENDED observed on the Redis channel with the
correct callUuid and hangup cause
