Hi,
I encountered next situation:
I have a PRI link from a provider; the did range is 0374599400-599; in my PBX the internal numbers are from 4400 to 4599. the provider sends to PBX last 3 digits
the numbers from 4500 to 4599 can be accessed from outside but the numbers from 4400 to 4499 cannot be accessed. (message from PBX, this number does not exist)
I have set up a speed call table so all numbers from 400-599 are send to 4400-4599.
Thanks a lot !!
