There are many ways to achieve load balance and fail-over in VOIP world. Each has its advantages and disadvantages, so the right solution really depends on your needs rather then your wants (needs vs wants).<div><br></div>

You can also try DNS based fail-over and load balancing, works perfect for us.<div><br></div><div>Thank you.</div><div><br><br><div class="gmail_quote"><div><div>On Fri, Jul 6, 2012 at 9:02 AM, A E G <span dir="ltr"><<a href="mailto:all.eforums@gmail.com" target="_blank">all.eforums@gmail.com</a>></span> wrote:<br>
