[Asterisk-Users] Asterisk: T1 hunt group setup

[Andrei (MPI)]

Hello everyone,

I'm sure someone had an experience arranging hunt-group setup for 
incoming calls on T1 PRI channels of Digium TE110P card.

For instance, I have main DID channel associated with number (555) 222 0001.
And I have whole bunch of other DID channels on same T1 card like (555) 
222 0090,  (555) 222 0091, (555) 222 0093.

My goal is when a call comes to the main number which is (555) 222 0001, 
to have it roll over to the next available T1 channel.
Or give busy signal to the caller if all channels are busy. To have one 
main number for all calls.

I thought this had to be done in Central Office for our T1 connection 
(like DID setup), and T1 provider keeps telling me that
this will be function of our phone system (Asterisk).

So, do I literally have to implement some sort of logic in 
extensions.conf, that would allow receive call on main channel and roll 
it over to a next available DID? And keep main DID number free all the time?

Please help!!
