my extensions.conf GROUPCALL => Zap/g2/12000221&Zap/g2/12000222&Zap/g2/12000223&Zap/g2/12000224 .... exten => s,1,Dial(${GROUPCALL}) exten => s,2,Hangup exten => s,102,Answer ... The Problem is, the asterisk output and the Master.cvs tells me that the Group was called but not who in the group answerd the call. Ok, I can see which Zap channel is connected but not who belongs to the channel because the channel assignment must be non static. Maybe there ist an other way to do a groupcall ? I will be happy about any suggestions.
