Hi, I'm a Freeswitch newbee and I'm trying to make a group conference call setup: Kamailio sends Group-Users:user1000;ip1000;.. ----------> Freeswitch I've seen that "conference_set_auto_outcall" does what I need, but the users must be registered: "2016-06-09 08:46:52.161319 [ERR] mod_conference.c:1389 Cannot create outgoing channel, cause: USER_NOT_REGISTERED". Without success, I tried setting: -> <user id="1000" cidr="IP1000"> in directory (maybe this should solve it and I'm doing something wrong) -> <param name="disable-register" value="true"/> in sip_profiles I can access the received header values in dialplan and get the user1000 and ip1000. Is there a way I could tell Freeswitch to add user1000 at IP1000 to group conference without needing to register them, just using the given IP? Also, what should I use if I want to keep a local "IP1000<=>x.x.x.x" mapping and avoid sending the actual IP in the Group-Users header? Thank you in advance, Stefan
