I have had VOIPo since moving in November 09. RoadRunner is our only option here and I wanted to see what others are using and having success with. My service was flawless from December through mid-March. (excluding any systemwide problems) As of late, and receiving a Grandstream ATA back in March, we have been having intermittent problems that at this point cannot be solved. ATA is connected to a Motorola SB4200 modem and I've tried different patch cables to rule out any physical issues.

I have been working with Tier II support and latest idea is that my pings occasionally going up to 150ms could be the cause, but I am at a loss since the call quality is fine and there is no packet loss. Usually calls will work fine for a few days and my tickets are closed, then the problems arise again.

I went with VOIPo for #1 price and #2 to keep our old number of 10+ years. I really want this to work, and I manage servers/networks for a living, but the WAF is not getting any better.

Anyway, back to the subject, who's your ISP and location?
