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

[Danny Nicholas]

Assuming that the ESI system phones are SIP protocol, you should be able to
do "native sip" dialing like 155 at foo or 120 at bar.  You would set up Regis in
asterisk with this line in the dialplan
Exten => 120,1,Dial(SIP/120 at esi,20,m)

In other words, you would treat the 45 ESI lines like softphones, where
Asterisk would talk to them using id at domain or id at address.

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!
