We are working on platform with several Freeswitch nodes and shared Freeswitch database accessed with ODBC. It works great but we have a problem with presence.

Scenario

Phone A is registered on node 1

Phone A subscribes to phone B presence. It sends subscribe to Freeswitch node 1.

Phone C calls  phone B. It sends Invite to Freeswitch node 2.

Freeswitch that is running on node 2  does not send Notify to phone A.

If phone C sends Invite to Freeswitch node 1 everything is OK.

Can anyone help ?
