Hi All,
         I am trying to communicate between two sip servers.The communication from external sip server user to kamailio user works but message from kamailio to external sip user is not reaching.

I get the following error in Jitsi

 "The above message could not be delivered
A network problem occurred. Please check your network configuration and try again. Error was: 408 Request Timeout"

Does kamailio do SRV lookup ? How do i force kamailio to use DNS SRV lookup.

Any clues ??
