Asterisk on FreePBX. Why is there no sound in the WebRTC (JSSIP) client?

Question

Asterisk

I'm trying to set up a FreePBX-based Asterisk to use a JSSIP client (tryit.jssip.net), but I've run into the following problem: No audio is playing on the browser side. At the same time, the sound from the microphone is sent correctly from the browser.
I want to note that when using the regular User Control Panel (ucp) in FreePBX, using the same jssip library, there are no such problems. Also, there are no problems with sound when using the sipml5 client.
It is clear that the problem is in setting up the jssip client, but I could not find out exactly what it is.

Answer 1

the library can be one, but different versions
compare debug calls from ucp and tryit
