FXO INTEGRATING WITH NORTEL PABX

[haarisalibaig]

Hi,

I have Cisco1760-V Routers with Vic2-2FXO cards on both ends connected on the Extension of the Nortel PABX, when i dial the extension No. on which my router is connected i am getting the tone but when i dial the extensions for the connected branches the dialtone is not getting cut. I am not able to reach any of the branches. do i need any specific configurations on my PABX or the Voice Interface

A connection trunk is not supported on Foreign Exchange Office (FXO) ports configured for ground-start.

So need to configure loop-start.

try to check the signaling: for your FXO card and signaling FXS PBX. this must be the same.
