[juyong li]

IP Centrex is generally accomplished by Applications Server as Halit's email says.

Hi Kemal, 

   

One of my experience is; 

A -> location -1 user 

B  -> location-2 user 

A calls B. A dials 4 digit. 

Call processed by Application Server and digit manipulation done
on core level. 

Lets say 4 digit becomes as regular B number. 

   

By the way, Does Centrex solution means PBX? 

If so then it is different J 

   

Regards, 

Halit

Hi all;



I am investigating about how Centrex work with SIP. If an enterprise customer
has a 2 different locations, how they call each other with short numbers(4
digit) ? Which SIP headers are used for it? Is there a standartization ? Does
any one have a solution documentation? How the big companies handle it?
