CM Inter cluster trunks with Voice Gateway..

[haarisalibaig]

Hi,

I have CallManagers & Callmanger express in many sites, all the local extensions are starting from 1 (1XXX). I want to enable calling between sites through VoIP. What is the best practice? Did somebody did this configurations before?

Please check the attachment for further understanding.

Do you hav a ccm in all sites if so u can use intercluster trunks otherwise u have to use dial-peer in GW's

create intercluster trunk with remote cluster IP and select that trunk in route pattern

route pattern eg:511.1XXX and there is an option for discard digits select "predot" there
