We have Cisco Call Manager 4.3 and all remote branches are using call manager for internal calls, utilizing 4-digit extensions.
Each remote branch has it's own PRI for their local and LD calls.
One branch, when placing local/LD calls, they are showing up as one of the internal branch 4-digit extensions.
For example, the other remote branches are showing up as the main branch 7-digit extension (DID associated to PRI) in caller ID.
The one branch in question is showing up as 7400.
Where would this br configured?
Each branch has a single router for connectivity to main site and the PRI is plugged into it as well.
