I have a tenant that has their main office using extensions 5xxx and is not on my system.
Each of their other offices are on my system and each facility uses a different extension set and is still adding to every month. [1-4]xxx is the extension range on my system.
I have a working trunk between the two systems and can dial back and forth just fine if I make an inbound route for all extensions that their main office would dial.
Rather than make 3000 inbound routes to accommodate all the possible extensions I'd like to use a range and point that range to all of that tenants extensions.
I added the DID _[1-4]xxx
assigned it to my tenant
I don't know how to apply or create the destination that would have it sent to internal extensions.
Any help would be appreciated?
