No audio when group paging

User can intercom/page to a single extension fine. However when attempting to page a group there is the beep and no audio. Reviewed the PCAP and found RTP is coming from the phone and reaching the FreePBX server, but the RTP doesn’t get sent from the server to any of the group members.

Well I was able to bench this and replicate. After the call starts, you hear the beep and the call simply drops. It’s not a lack of audio while the call remains up.

Looks like it may be a DAHDI problem, debug shows the device trying to use the meetme app which I believe is the conference bridging that requires DAHDI for it’s timing source.
