Interconencting 2 PBX's(TDM based) using T1 Trunk Voice WAN Int

Unanswered Question

Hi Experts,

We are planning to migrate our existing WAN to an L3 MPLS cloud.

We currently have 2 PBX's connected via dedicated links. These PBX's are pure TDM based.

Can we connect these to Cisco routers using the T1 voice card(part#VWIC2-1MFT-T1/E1) and route the trafic over the MPLS cloud. Also how do we tell the Cisco router at site A that it needs to send the PBX traffic to the router at Site B.

Would appreciate if someone can provide some guidance.

Yes. You also need the PVDM2 DSP module, like a -32 size. Then you need to get familiar with the voice configuration or hire someone that is.

The DSP are necessary for voip.

You can enter "pbx trunking" and get many results from the search box.
