[Asterisk-Users] callcentrum - call any, ring one

[Pavel Jezek]

I would like, that incomming calls displays (clid) on all ip phones in 
group (helpdesk), but only on user specific extension ringing...
e.g. helpdesk employee have number 310, 311, 312 etc.,
when incomming call to 311 line, only 311 line ringing, but on all other 
phones (310, 312) only display caller id, so that other emploee can 
eventualy pickup...
maybe use of dial with ALERT_INFO variable specifiing "silent_ring.wav" 
to quietly call other phones?
any better idea? e.g. special use of queue app?
