Telephony Engine
Telephony Engine is a app in the osFoundry community catalog. The core open-source telephony engine — SIP, IAX, PJSIP, IVR dialplans, conference bridges, transcoding, AGI/AMI/ARI APIs for custom call flows. Powered by Asterisk. Ships as a thin wrapper around the upstream image — for power users who want raw Asterisk without the FreePBX UI layer (use #219 if you want a web admin).

Documentation
# Telephony Engine
Raw Asterisk PBX engine — for power users.
## When to pick this vs #219 FreePBX
- **#219 PBX (FreePBX + Asterisk)** — same engine, with a complete PHP web admin
- **#220 Telephony Engine (this)** — bare Asterisk, configure via .conf files
Pick this when you want full control + version-controlled dialplans, no auto-generated config. Most users want #219.
## UDP caveat
Same as #219 — SIP signalling is TCP but RTP voice is UDP (10000-20000 typically). Container infra drops UDP. Real deployment needs UDP-friendly hosting.
## Packaging
Thin wrapper around the `andrius/asterisk` community image. Dialplan + voicemail at `/etc/asterisk` + `/var/spool/asterisk`.
