[OpenSIPS-Users] rtpengine transcoding

[Alain Bieuzent]

Hi Alexey,



I add the same default yesterday and solved it by deleting "codec-strip" flags.

rtpengine_manage("RTP/AVP replace-session-connection replace-origin codec-mask-PCMA transcode-PCMU ICE=remove");



I hope this will help you.



Regards

    And there's no any errors in RTPEngine log.

    I also found this https://github.com/OpenSIPS/opensips/issues/1288#issuecomment-367293070

    

    And tried as Razvan adviced:

    

    # i know that B side talks PCMU only, so i configre it

    rtpengine_offer("RTP/AVP replace-origin replace-session-connection ICE=remove transcode-PCMU");

    

    

    In this case - a little bit better - the call is not dropped, and I see how OpenSIPS/RTPEngine

    changes the codecs, and even see RTP, but going to one side only, but in different codecs.

    But still no sound in any direction  :D
