Has been calling for 3+ weeks now. just BEEPS.  repeatedly.  I called it back and the line is busy.  Am trying to figure out how to block it.  Has left 50+ messages of beeps.

Same here. Twice a day, no message. Even the few times I answered nobody spoke.

Same as several others.  They've called several times today alone.  No one is on the line.  Tried to call back, it is just a busy signal.

It's a DoD Computer Technology magazine. They call me every day, sometimes a couple times a day. I can't get off their list. I've asked at least a dozen times.
Today they said they're nearing a deadline.

This number calls 3-4 times a day and when I answer no one ever says anything...its really annoying

Calls 2 to 3 times a day, hangs on line but doesn't leave a message or identify themselves. HAs been calling for 2 weeks or more

These guys are incredibly persistent. They've been calling two or three times a day for the past couple of weeks. Occasionally, they hang on until voicemail kicks in, but they never leave a message.

I receive at least one call per day from this number.  No one on the line and no messages.

Called back this number.

It said it was a trade journal subscription renewal service.

Not sure if that is true, but that is the recording

Whenever I answer, nobody talks on the other end of the phone...Called twice so far today

I've received 2 calls from this number every day for the past 3 days while I'm at work. They leave no message.

Received two calls from this number within 1 hour. No voice message left.

I got two calls (so far) from this number today - no message left
