I've got 2 Freeswitch 1.6.2 setup on different servers: fs1.my-domain.com and fs2.my-domain.com.

I've got a DNS record with 2 A-records for the servers.

When two users ends up on he same server they can call each other. If they land on different servers they cannot. Then they endt up in voicemail.

I'm running the servers with a shared database in postgresql.

Should I do anything else besides db in the core for FS?

They are registrering with the same "main" domain which is fs.my-domain.com.
