K7: free fax/voicemail lines

Via Lifehacker:

Need a phone line to receive a one-time fax or voicemails on a particular project, auction, or job search? Free service K7 hands out 10-digit Seattle-area phone numbers that can answer calls with customized voicemail greetings or accept faxes. You can access both the audio files and fax documents through your sign-up account, and the only restrictions are a 20-message/fax limit (the site starts deleting the oldest after that) and an account wipe out after 30 days of inactivity. Other than that, you've got a free bin to keep your personal numbers private and still get at your messages.
