I have 4 voicemails on my landline all from Faxhhalt. It's a fax service of some sort from the Colorado area. The messages are those loud, piercing BEEP, BEEP, BEEP. Apparently they think I'm a fax machine. My messages, or I should say the caller id, are from 4 different numbers: 720-386-2781, 720-386-2681, 720-386-2820, 720-386-2669.  They just don't stop calling. They've been calling off and on for the past 6 months or so. I'm labeling them as 'fax machine' but I seriously think they're some sort of telemarketer targeting businesses via fax machine since most business owners probably won't give them the time of day on the telephone.
