Hi Nanang! Here is another strange issue: pjsip with SRTP=mandatory sends SDP with SAVP, but accepts also incoming SDP with AVP. IMO it should immediately send BYE if incoming SDP does not contain SAVP too. regards klaus Nanang Izzuddin schrieb: > Yes, it is rather strange since in pjsua SDP iLBC has higher > preference than PCMU, and the eyebeam supports iLBC as higher > preference too in its SDP.
