Kamailio is NOT a media endpoint nor a media gateway. It is a SIP proxy that routes call between two endpoints, gateways or proxies. What you seems to do is trying to originate a call from Kamailio to some provider, which will simply not work.
For Outbound Dialer service you need to setup some media gateway like Asterisk, Freeswitch or CUCM (Cisco Unified Media Gateway) etc. Regards. -- Muhammad Shahzad Shafi.
