301-771-0991

Call with hangup and no message. This is our Area Code, but we will block if another similar call comes in.

Additional information. It is listed as a VoiP call, so is very possibly spoofed.

Called twice within an hour.... No msg left.  Probably spoofed for sure.

No answer or response and then hangs up.

Recieved a call today, January 11th 2016 @ 12:00 Noon and CID displayed "Bethesda MD 301-771-0991" and as usual no VM was left. 😳  Since no VM was left, the call wasnt important to begin with. I have no idea as to who they are or why they are calling.

Its a security company. When you answer the computer starts to have a conversation with you.  If you don't respond, it asks if you are there.  If you say
"This call amounts to fraud" the computer hangs up.  If you call back, you get a recording saying all their operators are busy but you can be removed from their call list by pressing 5. We'll see if that works (I suspect not).

received call.  Did not answer.  No voice mail.  I've been receiving an unusual number of these type of calls since the beginning of the year.

Annoyingly-early AM call, 1/28/2016.  Male said call was "about home's security system."  I asked what company he worked for.  A:  Honeywell.  Q:  Where?  A: Dallas  Q:  What call center do you work for?  A:  <hung up>

Had a call center type call 15 minutes earlier from 301 211 1240   May be related.

This number showed up on our CID 2x today in addition to a few days ago.  I will start answering "Maintenance Desk" or "County Lock Up" and hopefully the calls will stop.

Another unwanted call from Besthesda MD 301-771-0991 on Feb.9th 2016 at 1:00 PM and as usual, no VM was left.

Assume you had a typo?  I had a call from 301-771-0991 this morning - no message.  This afternoon, the same number called, and I had a recording that somebody at my number had inquired about a leg or back brace.

Got call from this number on my cell phone.  Called back - no identification.  Only said that if I did not want to receive any calls or be removed from call list, to press "1" - which I did.  Then I called again - again, no ID.
