Have been receiving multiple calls from this number.  I tried calling it back and the number is not set up to receive calls.  They are calling my (recently acquired) cell phone.  I have received a number of collections calls on my cell from folks looking for "Carlos".  I suspect this 401 number is an automated dialer set up by collectors to harass deadbeats.

This number has called me three times in the past 30 minutes and as Martin said when you call back it's not a working #. They don't say anything when I answer and don't leave a message. It's Ridiculous because i've had this # for over 5 years..

Have received telephone call from this number for a couple days.  When I answer, no one responds.  Caller ID - Warwick RI

This number called me three times within a ten minute span. I don't answer unfamiliar numbers so after the third call I just saved them into my contact list and set them to go straight to voicemail.

Two calls so far today; truncated message or no message at all. Caller ID says 'Parked Numbers' -- telemarketing call for a number parking service??
