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.<o:p></o:p></p><p class=MsoNormal>Thanks;<o:p></o:p></p><p class=MsoNormal>John V. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
