Solved Intercom No Audio

[LinuxQuestion]

When I intercom a phone from another there is no audio, I can call that phones DID and have audio just fine. Just no audio on internal intercom calls. These phones are remote to the server, not on the same LAN.

Any ideas what could be causing this?

Forced audio through server and it fixed the issue.

Glad to see the issue has been resolved and thank you for sharing your solution. For anyone else facing the same issue, the "PBX delivers audio" option under extension settings must be enabled when phones are provisioned using STUN.
