Hi again, I have search a bit more in order to discriminate the problem, and I have realized that everybody goes out from a conference room, when a mobile phone o SIP call press '#'. Instead when a analog phone press '#', only this phone goes out. I'm working in Spain using a E400P, so I don't know if it's a zaptel configuration problem, an * version problem, a bug error in Meetme, etc ... I have search in bug-track but I don't see any bug about it. Can somebody give a direction in order to fix this problem?? I can send the q.931 debug file with calls. Thanks a lot. Regards.
