It is my understanding that this should only affect a single blade at a time and not carry over to other blades or MCU's. I do not believe it should affect cascaded conferences, but since you ran into a hard limit of 80 it is possible it may be the issue. > > I put this out there just as an thought. Maybe someone from Tandberg can clarify. As for GnuGK, the only thing I think might affect the calls is bandwidth limitation. Typically the bandwidth is set to 100,000 kbps so some endpoints would have to request more than 1024 per call. What was the bandwidth of the calls to the bridges? > > Scotth > > -----Original Message----- > From: pierlu [mailto:pierlu@xxxxxxxxx] > Sent: Thursday, April 14, 2011 10:48 AM > To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx > Subject: Help in understanding why concurrent video calls limit in my system is 80 > > Hi, > > today I run in a limit I was not prepared to encounter. > > I was managing a large videoconference and I could not go past 80 > concurrent calls.
