We can see from the trace that it is at least trying to connect the caller…sending the INVITE and then canceling some seconds later. As the other poster suggested, it would be helpful to see the sip trace. Also, after turning up the sip log levels (sofia global siptrace on) restart the destination phone/device for the called user, so we can see it register and see what address it registering and where it is coming from. That will be necessary to evaluate where the INVITE is being sent. Do you have some sort of outbound proxy in the scenario?

Whenever users are registrered on the same server they can reach each other. They register with the same domain (fs), because my DNS is using round robin between fs1 and fs2.

I've got a DNS record with 2 A-records for the servers. When two users ends up on he same server they can call each other. If they land on different servers they cannot. Then they endt up in voicemail. I'm running the servers with a shared database in postgresql. Should I do anything else besides db in the core for FS? They are registrering with the same "main" domain which is fs.my-domain.com <http://fs.my-domain.com/>. _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org <javascript:_e(%7B%7D,'cvml','consulting@freeswitch.org');> http://www.freeswitchsolutions.com <http://www.freeswitchsolutions.com/> Official FreeSWITCH Sites http://www.freeswitch.org <http://www.freeswitch.org/> http://confluence.freeswitch.org <http://confluence.freeswitch.org/> http://www.cluecon.com <http://www.cluecon.com/> FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org <javascript:_e(%7B%7D,'cvml','FreeSWITCH-users@lists.freeswitch.org');> http://lists.freeswitch.org/mailman/listinfo/freeswitch-users <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users> UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users <http://lists.freeswitch.org/mailman/options/freeswitch-users> http://www.freeswitch.org <http://www.freeswitch.org/> _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org http://www.freeswitchsolutions.com Official FreeSWITCH Sites http://www.freeswitch.org http://confluence.freeswitch.org http://www.cluecon.com FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
