The answer to your question depends on the QOS you desire. If you are concerned less with call quality, and more with price, then the previous solutions are certainly adequate. If call quality is important to you, I would recommend going with a VOIP provider that has a private network, that way your calls don't get switched to the public internet. When calls are switched to the public internet, quality issues are much more likely and random. WIth a private network your calls will be of much better quality and problems are less likely. Also, I have no experience with multiple Asterisk Boxes myself, but I have heard it can be tricky to cluster them as it seems you would be likely to be doing.<br>

I would look at setting up OpenVPN on each of the Asterisk boxen and<br>
running SIP between them. I have read that IAX2 is much better now,<br>
but I have had many major voice quality issues with it.<br>
<br>
With OpenVPN, all Asterisk boxen appear to each other as being on the<br>
same subnet. This gives you ease in using SIP and added security on<br>
many different facets.<br>
<br>
Thanks,<br>
