[Asterisk-Users] Groupcall problem

[Martin C.]

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.
