Dear All, I'm using kamailio as Proxy server for registration with RTP proxy as relay server for voice packets...I have an issue that when sending an Invite, the audio address in SDP (o header)is not RTP Proxy address while if I send another Invite to kamailio (second Invite), the RTP Proxy address will be present in SDP sent back by Kamailio... Anyone has a clue about what could be that matter?
