Hi, i am having problems debugging an SDP negotiation related to call hold. I receive a an INVITE with the following lines of SDP from an unknown user agent: ... a=sendonly m=audio 36884 RTP/AVP 8 101 c=IN IP4 10.184.13.134 ... PJSIP replies incorrectly with a 200 OK "sendrecv": ... m=audio 57928 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=sendrecv ... The "sendonly" is replied with a "sendrecv". According to RFC 4566 (5. SDP Specification, page 10), if a "a=sendonly" is put at a session level it affects all media sessions ("m="). Can anyone tell me if PJSIP supports the "a=sendonly" at session level ? cheers, Rafael Maia _________________________________________________________________ Hotmail: Trusted email with powerful SPAM protection. http://clk.atdmt.com/GBL/go/177141665/direct/01/ -------------- next part -------------- An HTML attachment was scrubbed...
