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? _______________________________________________ One technique that works well for two locations is to set up a high-availability group of servers, with one at each location. At each location, you arrange the SRV records for the SIP domain to prefer the local server over the remote server. The difficult aspect of making this work is that the two servers need to exchange the registration data they accumulate. But the necessary logic is in the sipXecs open-source system, and is probably done in other SIP registrar/proxies that support "high availability clustering".
