Turns out the initial one I was given was problematic and kept on recycling my connection. A problem in itself, but an additional "feature" that the modem has a built in DHCP server that is only active when your modem is not getting a proper connection. When that happens, the modem issues the private IP of 192.168.100.10, and the Grandstream registers with VOIPo with that IP. Then when my connection came back, a public IP is issued, but my ATA does not re-register. So, I would see 4 registration lines, and the VOIPo servers would get confused, and my phone calls would fail.

Kind of confusing, but you can follow the link out on DSLReports.com. I had a lot of VOIP heads helping me and I ended up knowing more about VOIP than I cared to!

At any rate, once I swapped out the DCP2203 for a new one, put the ATA inside my network and assigned it a private IP address, and VOIPo fixed a registration expiration parameter on their end, all was well!!

As far as advice/settings, the most handy feature in my opinion is the call routing. It's really easy to blacklist, or have certain numbers disconnected, or even forward pesky credit card scammers directly to the FCC with a couple mouse clicks!

That and the SIP phone. I can literally use my DroidX from anywhere in the world and make and receive calls from my home number.

Your home phone has become literally location-less.

Thanks for the response Dave.

I had some dropped call issues, but port forwarding, a static IP address, and some magic on the Voipo end have helped. Only one issue since, but support is always on top of things. I think anything like this takes some tweaks to get perfect, but once you're there, it's great. I'm confident I chose the right company. It's great to talk to real people when you need to.
