Just tested with the latest master, should be the same.
Are you sure the RURI as a `;` at the end in your test ?
``` $var(target) = "sip:conference@example.com:5080;"; ```
it seems it is not present looking at your logs : ``` kamailio[275]: 10(275) INFO: rtp_media_server [rtp_media_server.c:583]: rms_bridging_call(): parsed[sip:conference@example.com:5080][0] ```
versus mine ``` 5(520) INFO: rtp_media_server [rtp_media_server.c:581]: rms_bridging_call(): parsed[sip:conference@example.com:5080;][0] ```
I need to fix this pitfall in command arguments automatically ...
