I need to be pointed in the right direction.
My question is this: How do I set it up so that different users or groups of users dial out using the appropriate trunk?
I have a PRI that is configured by Southwestern Bell with 3 trunk groups. Incoming calls work fine and DID based incoming routing works fine. All outbound calls use the same phone number, though.
Channels 1-10 are in the first trunk.
Channels 11-20 are in the second trunk.
Channels 21-23 are in the third trunk.
Any pointers/help would be greatly appreciated.
