You can do round robin DNS. This however isn't the best way if you ask me, but it works somewhat. the main disadvantage with this method is not knowing the state of the server before you send calls through to the IP address that the DNS resolves to (i.e. it merely rotates IPs for a given Domain Name). Also, the return signalling path may not be the same as the forward path if the rotation has gone through to the next cycle, if you know what I mean, and you may have to do something with record route. You can also look into using DNS SRV, but I have yet to see a practical implementation of this. Not sure but there may be hardware solutions out there (e.g. a CISCO switch or something).
