Hi Denys, AFAIK read and writes rtpengine the complete sdp. So manipulating with the "classic" textops tools is more for RtpProxy. You can search for things but writing will done by rtpengine. I remove for example an codec with codec-mask. Or you can manipulate the avp you read from rtpengine (via modparam) in the request.
Did you try to *codec-mask= in the rtpengine calls (answer / manage)? * *So rtpengine takes care for the removal. * *It needs to know what to remove. * https://www.kamailio.org/docs/modules/5.3.x/modules/rtpengine.html#idm1459 Cheers Karsten Denys Pozniak <denys.pozn...@gmail.com> schrieb am Fr., 1.
