Hi All, I am in a situation where ICE controlling sent the INVITE with its ICE candidates mentioned in its SDP. After receiving the SDP controlled agent starts gathering its host,srrflx and relay candidates but while sending the host candidate it collects it's AP interface and send its SDP offer to controlling agent and during connectivity checks it is found that the host ip should be different and the correct ip and its peer address pair is nominated from both the side . But at this time controlled agent sends updated INVITE as "ice-mismatch". My question is when both the endpoint knows which candidate pair should be used then why controlled agent sends updated invite with ice-mismatch field in its INVITE. This eventually causes no media transfer across endpoints. Please let me know the remedy so as to transfer media across endpoints.
