[Freeswitch-users] Clustering/ storing registration server IP in DB

Trying to figure how to get info where (on which FS server) the SIP endpoint have been registered. There is an XML_CURL - but it get's only registration requests, and than not notified by the FS server, whether endpoint have been accepted for registration by the server or not. Should I listen for an proper event, and than update the DB ? Or there is a simplier/proper way to update DB upon endpoint registration? 2. Also - if there is a multiple regs allowed, and the same user have been registered on several FS server?
