Set up CESID for 911 call from one controller that uses oubound on another

[ZentheAlien]

I have inherited a cluster of 6 controllers located at different addresses.  They have reduced their outbound calling to one controller, which all 6 locations now use.   One location is having difficulty getting their CESID to show the correct address.  (The CESIDs are on each phone in Users and Devices)

I am thinking there might be no Emergency Route? 

Would that need to be programmed in the originating controller, or just the outbound controller?  (or some changes in both)   

Thanks in advance, from the newbie here.

You may need to set up an emergency route both on the trunk gateway as well as on the trunks between controllers. That's how my setup is configured, at least.
