RE: More on Vonage service disruptions...

Ah, and therein lies the rub.

Any sort of QoS frob that is implemented for VoIP
(or any other traffic for that matter) _must_ be
truly honored end-to-end, and at every intermediate
hop in between, for it to be "guaranteed"  -- otherwise
when traffic that you may designate as "higher quality"
is handed off to another administrative domain that
does not honor your traffic classifications, all bets
are off.

If you do not "own" the end-to-end network
infrastructure, there is no way to guarantee any
preferential handling of any particular subset of
traffic.

Offer a "Quality of Service" product to enhance voice over IP services.
