[OpenSIPS-Users] Check Live Peers on OpenSIPS

[Bogdan-Andrei Iancu]

Hi Ahmed,

if the destination number (called number) is not a local subscriber (a 
SIP user), you simply route the call to a PSTN GW (you do this re-route 
from the script)

To check if a user is a local subscriber, you can either check a pattern 
(like all my local users are alphanumeric, or all starts with 3345*, 
etc), either simply check if the user does exists in the subscriber 
table (see the URI module, the db_does_uri_exists() function:
    http://www.opensips.org/html/docs/modules/1.6.x/uri.html#id271131

Regards,
Bogdan
