Asterisk external media/rtp to janus gateway audiobridge - return audio issues

General

Hey All,

We have an asterisk bridge that has a sip channel and an external media/rtp channel to a Janus Audiobridge.

We have the audio flowing from asterisk to the audiobridge, but the return audio does not make it back to the sip channel.

I can see di-directional rtp traffic however the rtpmap do not match we see 107 from janus to asterisk, and 111 from asterisk to janus.

Not sure what we can adjust, would be great to identify the issue, any tips ?

The payload type to use via RTP is set when you configure the plain RTP participant, so it’s up to you to ensure it matches what Asterisk negotiates via SDP. See the documentation for more info.
