[Asterisk-Users] Incoming/Outgoing call question

[Chris Bagnall]

For handling outbound calls, your easiest approach is to have each business'
phones default to different contexts, so you might have the dialplan
arranged as follows:

[in-pstn]
exten => number,1,dosomething
exten => number,1,dosomething
exten => number,1,dosomething
etc.

[business1]
; internal calls within business1
exten => _2XX,1,Dial(SIP/business2-${EXTEN})
<handle outbound calls from business 1>

[business2]
; internal calls within business2
exten => _2XX,1,Dial(SIP/business2-${EXTEN})
<handle outbound calls from business 2>

[business3]
; internal calls within business2
exten => _2XX,1,Dial(SIP/business3-${EXTEN})
<handle outbound calls from business 3>

Then of course in the appropriate sip/zap/iax.conf files where you've got
the various business' phones defined, set context=business1/2/3 as required.

To handle incoming calls from PSTN numbers I'd define 3 queues containing
the users from each business, then set each of the incoming numbers in
[in-pstn] to go to the appropriate queue. You'd probably also want to
include in-pstn in each business' context for outbound calls so that calls
made between them to each other don't go all the way out onto the PSTN and
back again.

Chris
