I am currently bringing multiple sites into CUCM 7, all connected via IP. These sites have overlapping dial-plan's, and changing from 4 to 5 digit dialing is not an option.
I would like to utilize site codes. I found documentation that utilizes route patterns, but I do not see how a route pattern would work as I am not using a route list to reach the other sites. The other sites would essentially be seperated by partitions.
One option is to use a translation pattern to strip the site code and send the call to the DN in the proper partition.
Hope this helps.
