I currently have two of my remote office configure for VoFR using a MC3810 connected to a Mitel PBX. For cost reason only I planned to set a up a Point to Point T1 connection to on of the branches eliminating the frame-relay connecton. I was working with a CCIE and he had mention I could trunk the calls to the PBX but he no longer able to help me cause he has left that company. Can anyone directed or give me some guidance how to proceed with this. If you need addtional info please feel free to e-mail me.
The following two URLS have sample configuration for a T1 line terminating in a PBX and the backbone is a LAN environment , accordingly you can configure your own backbone. And the two examples have CAS and CCS for T1 line
