We’ve had a fully functional FreePBX running for the last 3 months, primarely used with WebRTC clients.
Now the sudden, these clients can’t make calls.
They can see incoming calls, but can’t answer them.
Softphones (Microsip) are working just fine.
Every module is up to date.
Verbose logging and pjsip logger doesn’t show anything, when I try to make a call from a WebRTC client.
One other thought. Did you start using IPv6 in your network? The webrtc client doesn’t work with IPv6, and just fails without a good error message. (Something I decided I would dig into at some point…)
In my case we are using the FreePBX UCP client from the LAN.
On further investigation, this is a client specific issu; Firefox works, Chromium Edge works, but Google Chrome is only one way audio (no inbound audio, but outbound audio works; e.g., the other end of the call can hear us, but we can’t hear them).
