Caller ID says "Private Name" following by unknown number. I didn't answer it and let it go to my answering machine. The caller hung up.

Numerous calls from this number; usually no message.  This time, supposedly left message--but was only very brief automated type noise followed by quick hang up.  Very annoying.

Picked up because awaiting an important call.  Automated voice asks for person unknown to us.  Have gotten numerous "wrong number" calls for the same person before.  Suspect it's some kind of "bad debt" collection call.

Got phone call from this number saying they're from Convergent outsourcing debt collector.
The company really exists but their phone number is definitely not this number and they wouldn't use automated message that they have "important message" that I need to call back.
Luckily I don't have outstanding debt now that I have to call you back about! Scam!!

Convergent Outsourcing, automated message, scam call
