Hi there, Now I could configure Kamailio routing logic based on service's short code (i.e route calls to 200, 300 to separated service's appliction (so call, app serv 1 and app serv 2). My problem is how can i configure Kamailio so that it can route the call from mobile numbers, such as calls from mobile number starting with 0988 xxxxx, 0978 xxxxx will be routed to app serv1 and the calls of 0976 xxxxx to app serv 2. So do you guys have an answer for me ? I would really appreciate your help!!!
