The c= line before the m= line is common to all media (if you have video or something else in your session) and the c= line after a m= line is specific to the media. So you should first check if the m_connections is non-NULL and if so, use that c= line, otherwise, you should use the sdp_connection. -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------- 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.
