Last 3 days, I've received about 10 calls from this number and others, all from the same company.  Most of the time, the recording is advertising FHA loans, as endorsed by Pres. Bush.  Obviously, it's BS.  When I press "1" to speak to someone, the reps either give me static that they are "just an operator," or they bluster and hang up.

Company names include:
Mortgage Pros
Mortgage Services
Warranty Services

I'm still trying to track these folks down.  I'll get 'em eventually.

In the meantime, I use this form a lot:
