Hi Mohammed,

I know how to setup IP telephony, what i need is a guide to integrate a pbx with cme, so that IP Phones registered with cme can communicate with analog phones connected to PBX system which is in another building

Hi,

The document which I provided include this as well. Basically you need to configure analog dialpeers out of your FXO ports

Can someone show me the connectivity

Right now i have this, and all hardware is on remote side..

IP Phones-->HQ CME Router---> SiteB Router---Fxo and Fxs---> PBX---> Analog Phones

lets say analog phones have extns 3xxx and ip phones have 2xxx

On site B Rtr:

dp 1 voip

dest-pat 2xxx

sess target 10.1.1.1 (HQ)

dp 2 pots

dest-pat 3xxx

port 0/1/0 (FXS)

is it correct? or it needs any more config.

Please help

That will depend on what the other side has to trunk, if it supports SIP/H.323, configure the dial peers pointing to it.

If it requires TDM, then connect the two systems and configure your TDM.
