I have 3 FS servers running together sharing UA registrations using ODBC Each FS server has a different "switch name": fs01, fs02, fs03 When a UA registers, it will randomly hit one of the 3 FS servers and "sofia status profile internal reg" will show something like: freeswitch@default> sofia status profile internal reg Registrations: ================================================================================================= Call-ID: 5e5392c0-932df231-3d1c57f2@192.168.99.69 User: 1004@test1.voip.demo.net Contact: "user" <sip:1004@72.43.207.130:5060;fs_path=%3Csip%3A72.43.207.158%3Blr%3Breceived%3Dsip%3A72.43.207.130%3A5060%3E> Agent: PolycomSoundPointIP-SPIP_330-UA/3.2.2.0477 Status: Registered(UDP)(unknown) EXP(2012-02-15 09:45:47) EXPSECS(3449) Host: fs03 IP: 72.43.207.158 Port: 5060 Auth-User: 1004 Auth-Realm: test1.voip.demo.net MWI-Account: 1004@test1.voip.demo.net Call-ID: 93aa045c-fd5f2941-d207cb1e@192.168.99.21 User: 1000@test1.voip.demo.net Contact: "user" <sip:1000@72.43.207.130:1666;fs_path=%3Csip%3A72.43.207.158%3Blr%3Breceived%3Dsip%3A72.43.207.130%3A1666%3E> Agent: PolycomSoundPointIP-SPIP_330-UA/3.2.2.0477 Status: Registered(UDP)(unknown) EXP(2012-02-15 09:29:41) EXPSECS(2483) Host: fs01 IP: 72.43.207.158 Port: 5060 Auth-User: 1000 Auth-Realm: test1.voip.demo.net MWI-Account: 1000@test1.voip.demo.net Notice the "Host" is the switch name.... Everything is working great except presence, it seems FS only sends a NOTIFY out when a call comes to the host that the UA is registered. So in this example, if UA 1004 gets a call on fs01 or fs02, a NOTIFY is not sent out, but if UA 1004 gets a call on fs03, the NOTIFY is sent out. Is there any way to remedy this?
