h1. Load-balancing through DNS SRV

You can distribute load across several nodes using "DNS SRV":http://en.wikipedia.org/wiki/SRV_record lookup.
Originating customers should be configured to use DNS SRV for each outgoing call. 

h3. Requirements:

* node count: 2+
* setup SRV records in your DNS zone to spread load
* setup your domain name in connection form for your customers
* notify customers about using DNS SRV for each call
* IP address count in data center = node count

h3. Limitations

* not every equipment supports DNS SRV lookup.
  Therefore, you won't spread load for those of customers, which doesn't support this feature.
