I've found experimentally this is not the case, at least when NUTAG_AUTOANSWER is set to false. The reason being, nua callstate changes when a re-INVITE is received and nua_i_state is issued with the new callstate plus the remote SDP which may or may not differ from the previous one. I solved this by keeping the previous sdp_media_t description and checking for changes with sdp_session_cmp(). Media stream descriptions can also be compared piecewise with sdp_media_cmp(), and so further down. Hope this helps, Mikhail ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
