Declining non-primary audio stream

[dotcom]

Hi All,

We are noticing a lot of these warning messages:

[2020-01-14 12:21:26] WARNING[15203][C-00000187]: chan_sip.c:10395 process_sdp: Declining non-primary audio stream: audio 13224 RTP/AVP 8 0 101 13

We have ALAW as preferred codec on our FreePBX and also on the Sangoma SBC.

Does anyone has an idea with could cause this?

Thanks for your help!

I can’t speak for the SBC but for chan_sip that will occur if it receives a call with multiple audio streams. It only supports a single one so it will decline the others. If things are working then you can likely ignore it. If things aren’t then you’d need to investigate the source of the call.

Thanks for your reply Joshua. I’m not sure if it’s currently causing any trouble.

We are investigating another issue and wanted to be sure it was not caused by the codec warning:

WARNING[4704] chan_sip.c: Autodestruct on dialog ‘a4d190c7-b153-1238-b3b7-021923280064’ with owner SIP/XXXXX-0000825f in place

That is not caused by the non-primary audio stream issue. That one is generally caused by something in the dialplan causing the channel to stay around for a long time.
