I just checked the source code - it is not possible to mismatch User-Name attribute - it is taken from generalID field of CAT token carried inside ARQ - no ambiguity. If it is incorrect - then maybe your endpoints use some non-standard mechanisms. Please send ARQ messages from the single call (both "originate" ARQ and "answer" ARQ). --- Zygmuntowicz Michal ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ List: Openh323gk-users@lists.sourceforge.net Archive: http://sourceforge.net/mailarchive/forum.php?forum_id=8549 Homepage: http://www.gnugk.org/
