I'm on Sprint, and the service was fine for a year and a
half. In recent
months it deteriorated to the point where more often than not
I couldn't
understand the other party at all, even though they always
said they could
hear me fine. Since my connection is symmetrical (t1, not
dsl or cable)
and my stats always say I have spare inbound capacity, I'm
sure it's not
at my end.

It wasn't latency, it was jitter and mostly dropouts. I
think they have
vast amounts of buffering so latency is tolerable if you can stand the
talking to the moon effect.

I have not tested jitter, but I will now.

I had some dropouts when one of my machines was "being bad",
and while it didn't usually disco, it did drop call content. I was
surprised it hung on to the call for as long as it did.
Longest I can attest to is about 25 seconds. I haven't gotten
around to figuring out why it held the session at all.

> I don't know about Vonage support. Never tried it.

That's the problem. It no longer exists. E-mail is auto-acked and
ignored, phone calls go through the usual voice jail tree
until you get to
the point when it would queue me for a person, where I always
got a busy
signal.

Calling the number to cancel was no problem getting through,
but by then
it was too late, I'd already ported the number to Lingo who
is slightly
cheaper and has a much larger local calling area, roughly Honolulu to
Helsinki.

Have you experienced any blocking on Vonage?

No, but my situation isn't typical of anything other than tiny ISPs owned by RLECs whose management know their customers personally.
