rtp set debug on And make an internal call between extensions. Observe the IP and negotiated RTP port#s for the 2-way, 2-channel audio between the two endpoints (internal or mixed). Audio issues are almost always related to some setting that is causing this negotiation to not be mutual agreeable. Be sure to ‘rtp set debug off’ when done as it will continue displaying (and logging) these RTP traces, and any calls of substantial length will generate thousands of messages each (even when not in the asterisk CMD prompt mode).

Asterisk is version 16.13.0, and FreePBX is 15.0.17.55.
There are four Grandstream VOIP phones as extensions, all registered as PJSIP, and there's one SIP trunk going out to the world. The PBX and the phones are on the same subnet. All of the phones can receive audio, but none can send audio to another device. 1. Call the speaking clock at *60, it works just fine, Allison's voice is heard. 2. Call from one extension to another, no audio. They're probably both receiving audio, but neither can send any. 3. Make a call outgoing on the SIP trunk, the local phone can hear the other party but cannot be heard. 4. Receive a call from the SIP trunk - again, the phones can hear the other party, but cannot be heard. I don't think it can be any kind of NAT issue, since the phone extensions and the PBX are on the same subnet. Aside from the phones not sending audio, everything seems to be working. If I bring up Asterisk Info in FreePBX it shows the extensions and the trunk using PJSIP with ONLINE status. It's got to be something simple and dolt-ish I'm doing or have failed to do. Any ideas?
