asterisk users - Jul 2010 - Dialplan question when using a round-robin

Hi all,

i have a question regarding the dialplan when using a DNS round robin for simple
load balancing.

When i have 3 identically configured Asterisk servers and one DNS round robin
populated to the clients

Server1
Server2      -> round robin voip.example.com
Server3

where all 3 servers are connected via an IAX2 trunk among each other, how can i
determine within the dialplan on which of the servers a client is actually
registered?

So when user A wants to call user B and user A is registered on server1 and user
B is registered on server2, afaik the dialplan would need to look like

Dial(IAX2/server2/${EXTEN})  

But how can i determine on which physical server user B is registered?
Or is there an other, better way to achieve this? Maybe in replicating the
registrations between all 3 servers?

Thanks in advance for advise.

as a quick option you can use

Dial(IAX2/server1/${EXTEN}&IAX2/server2/${EXTEN}&IAX2/server3/${EXTEN})

call will connect to whichever is available & answer, others simply ignored!
