asterisk users - Jan 2006 - interfacing w/ a legacy InterTel PBX

Greetings all -

I'm interested in using an asterisk box to supplement and add VoIP
capabilities to our legacy InterTel Axxess PBX.  After searching
through the list archives and through google, it seems that the best
way to go about this is to connect the two systems via a T1.  Is this
correct?  The PBX currently doesn't have any VoIP capabilities, so
that's not an option for connecting the two systems.

I can put another T1/PRI card into the PBX and a Digium TE110P in the
Asterisk server.  My understanding is that this would give me 23
concurrent conversations between the servers.  One question I have is
that since I'm using a PRI, will CID information be able to flow
through the two systems?

Thanks!

What interface is your current PBX using?

Since there is an Asterisk SetCallerID application, I guess it should!

I connected an Asterisk server and a legacy Alcatel PBX using this method.
Remember that crossover cable is not an Ethernet crossover cable but a
special one (search the wiki).
In Italy, alphanumeric caller IDs are not used, only numbers and I'm able to
use them between two systems.
