Cisco 2911 Configuration for PBX

[30n30w]

We would like to eliminate a telco T1/PRI between the two pbx at the two sites and use the 2911's as the T1 extender instead. So it would be: PBX < - > 2911 <-> Private Ethernet <-> 2911 <-> PBX

I'm a PBX guy learning the Cisco world, so a basic example config would be very helpful - the PBX's use a PRI config - 23 channels plus 1 D channel for signalling. The 2911's have Wic3 T1 cards already in them (not used)

Thanks for any advice!

Hello,
With your network diagram, you can do setup to simulate T1 PRI provider by doing tunneling Q.SIG or Q.931 over SIP.

Thanks but no SIP involved in this scenario; just using the cisco routers to carry the T1/PRI between the two PBX's.

If you don't want to involve in VoIP (SIP/H323) then I'd suggest you to use bridging. Refer to this link:
