DDI à DDNS à kamailio & asterisk in one server [192.168.1.77]. kamailio passing DDI to asterisk, but its sending to wrong context. If any of the sip users is registered, the calls were sending to registered user context. If no sip user is online then calls has been send to kamailio-trunk. How can I get all DDI to kamailio-trunk? How can I solve this problem? Many thanks Sathees
