[asterisk-users] VOIP provider reliability

[Kenneth Padgett]

Anyone out there using VOIP for business class inbound/outbound
services? I've found my VOIP provider to be less than reliable, SIP
registrations timeout, calls drop, they claim IAX2 is too buggy (I
find that hard to believe), and pretty much blame all problems on
other circumstances and don't actually fix their problems. Their auto
rollover doesn't even work right, so if my PBX is down, I just miss
calls half the time. This isn't my first provider either, I've tried a
couple now. Controversy, I've never had problems with my Vonage line,
and I've had them for 3 years now (I know, unfair comparison).

Anyone out there with better experiences?

I'm mainly interested in hearing if people are replacing land lines
with VOIP in a business setting and optionally what setups they've
implemented to minimize or eliminate downtime (backup system, call
routing, multiple SIP providers, etc).

I realize this isn't the business list, so if you're going to
recommend a provider, email me off list so as not to anger the
natives.

Thanks!
