Used this approach a bunch of times for various projects. You can as well convert SIP Trunk to PRI and feed it into the PRI Port of the PBX using an ISDN VoIP Gateway.

I thought the phone extensions were programmed on the traditional pbx. When dialing an extension through the at a device, how does the traditional phone system know what extension to route a call coming on line 1 to?
