Seems like voipbuster is doing round-robin DNS for redundancy. Bad 
choice with asterisk, since asterisk only looks up DNS on startup or 
reloads.

You could read out all the entries in the DNS zone and create your own 
list of entries in /etc/hosts, and then create multiple asterisk peers: 
voipbuster1, voipbuster2, etc... Then you can use regular dialplan logic 
to cycle through all of them.
