This is a voice capable router, so you should be able to. Doing hairpin analog calls should be something very manageable.

but 1721 is not a voice router...its a data router

Hi Eldho,

Apologies. The data sheet I was looking at grouped the 1721 with the 1751-V. It didn't sound right, but I wasn't going to argue with a data sheet.

So the correct answer is no - you would need a 1751-V minimum to connect two PBXs together.

I guess the two PBX are at different sites. If so, then you shoud be able to integrate them using two VG or two Voice capable router with analog or digital trunks.
