There is no such product named nm-1cue1-pri.


What router type do you have in all locations ?

You need either vwic-2mft-e1 or vwic2-2mft-1e1/t1. These are two-port E1 cards, one port connects to pbx, other to wan circuit.


Also you need the dsp module, called pvdm2-xx where xx is the number of voice channels you need. Available sizes are 8, 16, 32, 48, 64.


Hope this helps, please rate post if it does!

It can be lengthy, if you never configured voip I suggest you hire someone with experience as it can be frustrating the very first time.

Write back onece you've the hardware in palce.
