Advice/suggestions about getting access to some sort of support would help, I've never had a response to any messages sent to the ooma folks through their "Contact Us" form. Is there someone I can e-mail directly or maybe PM via these forums?
Here's my results from http://www.whichvoip.com/voip/speed_test/ppspeed.html if that provides any clues; from what I've read here it sounds like my problem is probably local switching, not a network connectivity issue?

Friends don't remember what Landline Integration was or why we did it.
Getting my call quality problems escalated to a tier 3 tech seems to have gotten them fixed; the folks answering the phone just keep wanting you to futz with QoS settings, say maybe it's your phone, etc.
But you need to call soon after the problem comes up - when I cited a call from about a week earlier that had been problematic, they said the info needed to troubleshoot was already gone.
