I'm trying to program ability to send different calling numbers over one T1 PRI23 so customers see the company name that is calling out. There seems to be only one entry allowed for Area Code, Office & Subscriber number though. I thought I would be able to set-up something like trunk groups and dial 81 for one company & 82 for the other.
I am using the 576 programming software to program the switch.
Anybody know how this can be accomplished?
