I have 100+ extensions and about a dozen of them have unique emergency CallerIDs configured.
I have one emergency route with two trunks, where trunk A has individual E911 addresses configured for each of the emergency callerIDs, but trunk B has only one E911 address configured for one CallerID.
So whenever there is a 911 call failing over to trunk B when trunk A is down, I need to force a specific CallerID on trunk B (and not allow the extensions’ emergency callerIDs, cause those are not configured for E911 on trunk B, only on trunk A).
Normally for all non emergency calls, trunk B allows all CallerID, which is desired.
I don’t see a way of doing that from the GUI, so my question is how would I do that using custom dial plan.
Can I include custom dialplan AFTER a trunk was selected?
So the logic for the custom dial plan would be: Do nothing special on 911 calls if trunk A is available (GUI settings are sufficient), but set a specific CallerID if trunk B is selected.
