Need Help on PSTN fall Back

[rfateh]

Hi ,

In My IP Telephony network i have a Remote site witch has a 2610 router with 4 FXO . the FXO ports connected to PSTN

Right now all Voice traffic will come to my Centralized site using WAN Link

After my WAN LINK goes down i want to do PSTN Fallback So if any calls comes into my 2610 it will try to do the PSTN Fallback and From PSTN it dials the number of my Voice Gateway in Centralized site and try to connect the calls Using PSTN lines to Centralized site ,

Caller1-->PSTN--->FXO port Remote site-->PSTN-->FXO PORT Centralized Site

i dont know how to enable fallback to use FXO ports for dialout and Connect the calls to centralized Site

BTW i serached cisco but non the documents helpd me ,

Thank you

Hi,

First, enable fallback like this

call-manager-fallback

ip source-address port 2000

max-ephones X

max-dn X

If you want more features, you have to add commands.

Second, make dial-peer for calls
