It seems to load the exact same contacts every time. When I click on Sync, it loads part of the contacts. To the right of Sync it shows "loading....." and never changes.
LOL, the 304 contacts is every one we know, including 110 businesses. And of course every contact has at least 2 listed numbers. I have one collection company (Portfolio Recovery) with 51 numbers listed, all of them blocked. I love google voice.
