- 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
