I bypassed the router and ATA just to show that it was not specific to those devices.

Since this is only a minor annoyance and, as you mentioned this is new technology, I didn't bother writing a ticket. I saw this thread and thought I'd share my experience.
Unlike you, I opened a ticket for it. After all, this may be an issue that, sooner or later, may lead to a bigger problem.
I also bypassed my router by hooking up the VOIPO adapter to the cable box. That didn't solve the problem. I then took my VOIPO adapter with me and tried it on a friend's cable modem (different ISP) - same problem.

The funny thing is that everything on my end used to work fine until Saturday, July 28th, 2012. Nothing changed on my end, so, if VOIPO could track down what changes they made that day (or the night before) on my line, it may lead to a solution.
