[Freeswitch-users] NOTIFY not sent in multi-FreeSWITCH setup

[Vik Killa]

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 at default> sofia status profile internal reg

Registrations:

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?
