[Asterisk-Users] Question: "When i Diall a group"

[didier]

Hello,
This question is probabely recurrent, i apologize, but i haven't found a 
limpid explanation (for me)  in mail list, google, and hum.... source 
code):
When use the Command DIAL to ring a group, WHERE is stored the name of 
the 'winner' who pick up the call ? ($variable = ?), and, step beyond: 
WHEN (or on EVENT = ?) could we get this variable ?

many threads but nothing very very decisive (use event link, importvar, 
dialpeername (broken), bridged etc etc)
Thank's for your help to get the right process

Best regards
