[Asterisk-Users] T1 Technology and VoIP Gateway Primer

[Callum McGillivray]

Hi Matt & everyone else,

We have also been steering toward using a gateway for our large 
installation.

Ours differs from your significantly in as much as our setup will 
involve 8 apartment buildings located throughout the CBD.  Each 
apartment building will have as many as 600 extensions (rooms) with an 
Asterisk Server in the comms room in the basement.

Incoming and Outgoing calls are going to be trunked from the Asterisk 
box along a fiber link back to our core exchange, where the calls will 
be handed off to a gateway machine (Cisco?) which will have an 
impressively large number of PRI's plugged into the back of it.

My (very vague) examination so far tells me that I can use something 
along the lines of a Cisco AS5400 (a couple of which I have kicking 
around here in the office).

Has anyone had experience in handing off / receiving calls from a Cisco 
AS5400 with Asterisk ? 

How is it done ?

Matt, is this similar to the idea that you have for your project ?  What 
Cisco hardware have you looked at so far ?  How many E1/T1 lines are you 
going to have terminating on your setup ?

Cheers,

Callum
