[SR-Users] Ring Groups not publishing status for BLFs

Hey there Kamailio Users.... I have followed the guidance of:  https://kamailio.org/docs/modules/5.1.x/modules/tm.html I have created a dial code '8888' and will change the URI and add a few others... ------------ request_route { if($rU=~"^8888$") {     seturi("sip:a@example.com");     append_branch("sip:b@example.com");     append_branch("sip:c@example.com");     append_branch("sip:d@example.com");     t_relay();     } } ----------------- It works great BUT.... There no PUBLISH events sent out, as a result, no BLFs flash,etc... Also, no audio on the line when I pick up the phone. If I call the dest directly, everything works as expected.. Any ideas? Jerry
