[TriLUG] Site to Site VPN over the net? Good enough for VoIP?

[Chad Thomsen]

Was wondering if anybody is doing this successfully at there BUSINESS (not
looking at home usage).  I have a 7 site network and was thinking about
converting from ITC Deltacom frame to speakeasy.net DSL (since they offer a
CIR like service) but was wondering if very many folks have been successful
with it.  BIG question is performance.  What happens if the traffic on the
internet backbone is really heavy?  Would it not effect the performance of
the VoIP?  Speakeasy.net can gaurantee minimum bandwidth to and form the
"intenet cloud" from each location but once traffic is traveling accross
that cloud you are at the mercy of the internet backbone.

Any feedback would be appreciated.

Thanks!
