Yes! As Sunil pointed out, a=rtcp: <port> is used for specifying separately the port for RTCP (generally used if rtcp_port != rtp_port+1) which is in accrdance with RFC 3605. a=inactive applies to the whole RTP stream.

A= inactive is not specific only for RTCP it is for RTP. RTCP will still be streamed as you have proper connection IP and port specified. Only RTP will be inactive. Please refer to Offer answer RFC 3264 for more details.

Basically after the initial offer my UAC sends the re-invite where its changed the connection ip and the port and UAS sends the successful 200 OK and its get the ACK in the correspondence of 200 OK. Now after a while my UAS sends the another INVITE to put the call *on-hold* and getting the below SDP offer. But as far as i know that this is not the correct offer to put the call on hold, because we are getting "INACTIVE" for rtcp and media attribute m=audio 60492 RTP/AVP 0 101. v=0 o=- 21 3 IN IP4 10.64.1.99 s=session c=IN IP4 10.64.1.99 b=CT:1000 t=0 0 m=audio 60492 RTP/AVP 0 101 c=IN IP4 10.64.1.99 a=rtcp:60493 a=inactive a=label:Audio a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 And getting the below SDP from SBC in 200 OK. v=0 o=sg2-lax 1266796350 1266796353 IN IP4 192.168.135.40 s=sip call c=IN IP4 192.168.135.41 t=0 0 m=audio 55444 RTP/AVP 0 101 a=inactive a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 Could any one please help me on this whether this is the correct or not.
