[asterisk-users] Bridging old system (ESI IVX E) with new Asterisk server

[Eddie Mikell]

All:

My company has an existing ESI IVX E-class system with 45 phones.  I can 
add one more card, to expand it another 6 phones, but it's $8000, and 
then the system will have to be replaced.

I have the Asterisk server up and running, with 2 sip lines from the 
local phone service.  (Thanks to you guys, it is working great!).  I'm 
pretty sure this is the way the company will move, and I've have 
installed 8 phones for different people to test.

My question is this:  Is there some way I can bridge the two systems 
together, even temporarily?  So if Jake is at extension 120 on the ESI 
system, and Regis is at extensions 155 on the asterisk server, Jake can 
call Regis and vice versa.

I've pondered on this over the week-end, but don't see an easy way to 
handle this.

Thanks!
