All; I build a conference server using Asterisk 1.8 and the third party module app_konference.so. I would ask on their forum, but the forum seems to be pretty dead. The problem I am having is that when I have conferences that have a lot of members, say 100+ users, the DTMF seems to not work. For example, pressing the digit to mute all conference members does not do anything. When I have smaller conferences, say 25 members, everything works the way it should. I would greatly appreciate any input at all on this issue. Thanks; John V. -------------- next part -------------- An HTML attachment was scrubbed...
