[cisco-voip] E1 trunk

[Paul]

Now we're just getting into semantics. . .
if you mean can remote CCME boxes make calls out of a remote office? Yeah sure 
they can...if you mean can a CCME box physically control the remote E1 PRI's 
d-channel? No, that's probably not going to happen.

Dear Sir, 

Am i correct in my assumption that, a remote CME cant seize a remote E1 channel 
? I know this sounds stupid but just need to confirm this point.

Can you kindly confirm it

Making calls out of the E1 PRI remotely is perfectly doable AFAIK. You just have 


to be careful about your voip dialpeers. I don't remember any requirements for 
CCME to have local trunks but then again, I don't think I'd design a system that 


way since all of your PSTN connectivity will die as soon as your WAN dies.

Sir your assumptions are 100% correct. Sorry if i didnt ask the question 
properly, but even then i am able to conclude that there is no way to seize a 
channel of E1 PRI remotely. 


Thanks alot

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.
