I know this is slightly off-topic for this forum, but I'm wondering if anybody else has experience with not being able to call a Google Voice number from a land line. I've tried to call my GV number from multiple land lines in my area, and I keep getting a "You must dial a one first" message. Dialing a one first doesn't help either. Google has a troubleshooting page to report issues (http://www.google.com/support/voice/bin/answer.py?hl=en&answer=115142). I've filed a few different reports, but have received no response. Anybody have any insight into this?
