[asterisk-users] Asterisk Load Balancing

[Darren Sessions]

One other thing you could try would be to use OpenSIPS and use a  
standard config that routes to a hostname (with a creative failure  
route setup). You'd then setup the hostname in DNS as multiple SRV  
records reflecting your pool of Asterisk servers (set your TTL very  
low for these records). You could have something like sipsak send test  
messages every 30 seconds or so to each of the Asterisk servers. If  
one quits responding, then the monitoring app updates your DNS servers  
removing the effected Asterisk server from the DNS pool and  
effectively from the usable gateway pool.

I actually wrote one of these ages ago that worked fairly well with  
a10 calls per second SER server. How many calls per second are you  
looking to process?
