He's using Google Voice, which uses XMPP, not SIP.

He has a Tomato router, so all ports are open by default. Also, blocked ports would typically manifest as one-way or no audio, not garbled audio. If some of the audio arrives, then the port is open.
To Wilbur:
Poor outgoing audio quality on both incoming and outgoing calls is 99% of the time due to some other device on your LAN using too much upload bandwidth. You can test for this by disabling wireless on your router, and unplugging all wired devices (except your OBi) and making a test call. If the symptoms do not appear, the problem can be solved permanently by setting up QoS.
If your NetTalk Duo and the Echo test always work properly, it is possible that you're the 1%. By any chance were all the test calls you made in the same area? If you make a long distance call, does the problem still occur? It is theoretically possible that Google Voice's routing to your town has problems, however the odds of this happening are fairly remote.
Either the problem will go away with no other devices connected to the internet, OR the VoIP simulator test will show poor results, OR the problem will not appear when you make a long distance call. I can't think of anything else that would cause these symptoms.
