Reliable provider, affordable price
Flowroute is very affordable. I've been using them for over 3 years and haven't had any problems with reliability, uptime, or call quality.
They have been very helpful in diagnosing issues I've had with various asterisk based VoIP systems. Tech support, while efficient, is not very fast when submitted through email/ticket.
I submitted a bug report once and was told to expect to receive a follow up within a few weeks. About 1.5 months later, the issue was fixed, but I was never notified. So, if you notice a problem with their service/systems, don't expect notifications when they fix it.
