If I understand correctly, when you receive 200 Ok, all branches will be finished. So, you don't need to cancel them.

Hi I want to use kamailio with sems for early media generation. For that purpose I write a service route that when an invite received by kamailio it triggers that route in that route I fork the call to the sems and continue to the calle when I receive 200 ok cancel all other branches. But no media between 2 call ends please help me. I know something is wrong in my logic

route[SERVICES] {

rewritehostport("127.0.0.1:5080");

         append_branch();

         t_on_branch("1");

         t_on_reply("catch_200");

}

branch_route[1] {

        remove_hf("P-App-Name");

        append_hf("P-App-Name: early_announce\r\n");

        append_hf("P-App-Param: B2B=no\r\n");

}



onreply_route[catch_200] {

             if(status=="200") {

                     if (t_cancel_branches("others")) {

                     xlog("cancelled all branches\n");

                     }

            }

}

Thanks.
