I am using multiple registrations, and had initially kept the bridge calls using the 'user/' syntax. Presence was working with this, however i noticed that when I used a simultaneous brige separated by commas, some of the extensions would ring one registration and not the other. So I switched to the sofia_contact bridge method and this fixed the issue. However, when using sofia_contact to bridge, I noticed that presence does not seem to operate. I turned on debug presence and the only thing I see that may relate to an error is: 2012-10-06 13:13:50.183942 [WARNING] sofia_presence.c:4222 check_subs: external is passive, skipping 2012-10-06 13:14:11.153694 [ERR] sofia_presence.c:3343 DELTA 120 2012-10-06 13:14:11.153694 [ERR] sofia_presence.c:3395 check subs sql: select count(*) from sip_subscriptions where call_id='4agoj24x@snom' and hostname='euro-pbx' and profile_name='internal' [1] 2012-10-06 13:14:11.153694 [ERR] sofia_presence.c:3417 re-subscribe event message-summary, sql: update sip_subscriptions set expires=1349543771,contact='"Shop" <sip:102@192.168.1.13:3167;transport=udp;line=5r26s2>' where hostname='euro-pbx' and profile_name='internal' and call_id='4agoj24x@snom' and profile_name='internal' 2012-10-06 13:14:12.183897 [ERR] sofia_presence.c:1982 SEND PRES NOTIFY: file[sofia_presence.c] func[sofia_presence_mwi_callback] line[2896] profile[internal] via[] ip[192.168.1.13] port[3167] route[sip:user@192.168.1.13:3167;transport=udp;line=1k5l6w] contact["Front" <sip:101@192.168.1.13:3167;transport=udp;line=1k5l6w>] to["Front" <sip:101@192.168.1.200>;tag=TQK1cNoQcA2H] from["Front" <sip:101@192.168.1.200>;tag=06l8nn] url[sip:101@192.168.1.13:3167;transport=udp;line=1k5l6w] call_id[9mgy45bh@snom] expires_str[] event[message-summary] ct[application/simple-message-summary] pl[Messages-Waiting: no Message-Account: sip:101@192.168.1.200 Voice-Message: 0/4 (0/0) ] -- ******************************************* BRETT WILSON IT DEPARTMENT LAUNCH 3 VENTURES, LLC 134 Myer Street Hackensack, NJ 07601 PHONE: 877.878.9134 FAX: 646.536.3866 EMAIL: Brett.Wilson@launch3.net AOL IM: Brett.Wilson@launch3.net www.Launch3.net www.Launch3telecom.com *******************************************
