Hello, I have a problem with some calls where the rtp stream from the other side changes the rtp ptime multiple times.

I make a call with the sdp line "a=ptime:20" but the initial rtp comes with 40ms ptime.
FreeSWITCH detects it and changes the ptime to 40ms and all works ok.
Later in the conversation, without any re-invite, the rtp stream changed to 20ms. At this moment, FreeSWITCH does not detect the change and the audio sended by FreeSWITCH to the other legs is choppy.


I think that the problem is on the other side, but the other side is a big operator and always this is a problem to solve issues.


I tried to set "rtp_media_autofix_timing", but if I set this property, the first part of the conversation is discarded (ptime at 40ms, silence in my phone) and later I can listen the audio (when the ptime=20ms).


Is there any solution for this?


Best regards

Tell the other side to fix their brokenness maybe?  How did you try setting the flag?

In the future try setting the variables as a global too, as a step to ensure you have it where you think it should be.

Hello Jose

Sorry to interrupt the thread, but just wondering if you think adding a maxptime attribute in the SDP may be a work around for you?
If you set this to 20, the switch between 20&#x2F;40 should not happen.

Kind regards

Sameee

Yes, I know that the problem is from the provider, but its response time is bad.
I setted "rtp_media_autofix_timing=false" for testing, but when I setted, the first packets (40ms) are ignored and when the ptime is 20ms I listen to it. I think this is the correct behavior according to my understanding, so I can't solve the problem with the buggy provider.
Best regards

You're assuming that the other size is also following the rules, that is rarely the case.  But not any harm in trying.

How can I set the maxptime value?

Setting the codec like this PCMA@8000h@40i?


Best regards
