[cisco-voip] E1 trunk

[Paul]

The problem here is that you haven't provided a full scope of your 
infrastructure.

I have spoken about your design with these assumptions:
One E1 PRI at HQ using CCME
branch offices have no trunks analog or digital.
branch offices using CCME
Four offices all using CCME with solid connectivity amongst the four office with 
either meshed/hub-spoke topology

Dear Sir, 

Did you mean that if i have a FXO at my HQ, i shall be able to seize it on a 
remote CME according to the dial peer you defined ? i thought it certainly is 
not possible since, CME shall collect all the digits prior before sending it to 
remote router right ?

How can it seize a trunk when the digit collection is not complete ?

To my knowledge this is not possible with a PRI. If you had analog trunks (FXO) 
you could have a dial peer with a destination pattern of 9 and forward digits of 

0. When a user pressed 9, it would match, seize a trunk, and provide dial tone 
from the carrier.

It sounds like you are trying to make CME function as a key system.
