New Testube Voicemail Feature

I just added a new voicemail feature to the site, courtesy of the folks over at K7. I had heard about this service from a podcast by Jay Moonah and decided to check it out. It is a free account and basically works like a fax/message to email service. The phone number is 206-202-3848. I used to have a similar service via my IP phone at my last place of employment.
Anyone can leave a voicemail and they convert it to an audio file. That audio file can then be saved and posted on the website as part of an audio guestbook, or it can be included in a podcast. For example, a visitor to the site might have a question, and I would be able to include that question (and my answer) in a future podcast.
It's a great idea. My only complaints so far is that I haven't been receiving the email notifications. When I left a test message, I had to log into their site to retrieve it, whereas my account settings are supposed to deliver a copy to my inbox, as well. That isn't happening. But I can't really complain because it is a free service. Having to log in to their website to check messages every so often isn't going to kill me.
