<p>Greetings!</p>
<p>I've been playing around with "clustering" some Asterisk servers for sake of fail-over and load balancing with DNS round-robin, and came to one problem.</p>
<p>If I have, say, 2 servers, and clients register either on 1 or 2, how can I route extensions between them? I mean, if today user with extension 101 is registered on server1, and tomorrow he will register with server2 - how would any of servers know where to route it?</p>
<p>As some examples, if I have only 2 servers, things are not so bad. I can use Dial(SIP/101&SIP/server2/101) on server1 and vice versa. OR, I can check the hungup code, and if it's 34 (or whatever I get when I try to dial unavailable peer) - try it on another server.</p>
<p>But I guess things get tricky when you have 3 or more servers, and besides maybe this solution is not the best one. Could you share some knowledge on this, please?</p>
