But now I tend to agree with Michal, because there is 462 ms (-with-ifs) and 133 ms (-test) between the events. 1. Were you doing any filtering in Ethereal that might have discarded something relevant? 2. Are there multiple IP addresses on the network interface? 3. Are there any other network interfaces on the GK machine? If so, try running Ethereal on them, too. Of course, you should first test with H.245 tunneling disabled, as Michal suggested. You will need to forward the H.245 ports across your company NAT. --Stewart ------------------------------------------------------- This SF.Net email is sponsored by: InterSystems CACHE FREE OODBMS DOWNLOAD - A multidimensional database that combines robust object and relational technologies, making it a perfect match for Java, C++,COM, XML, ODBC and JDBC. www.intersystems.com/match8 _______________________________________________________ List: Openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Archive: http://sourceforge.net/mailarchive/forum.php?forum_id=8549 Homepage: http://www.gnugk.org/
