Received numerous calls from this number.  Usually while I am not at home.
Very annoying.

Calls numerous times. Does not leave message.  
Don't know anyone in Washington DC
Very annoying

Called this number back immediately.  Got a "disconnected - no longer in service" recording.  Very strange.

Have called every day, for the past couple of weeks. This is a robo-call, as they hang up one ring before the call goes to my answering machine.

calls, leaves no message

calls, no message left.

get calls, no message left, says "wireless caller"

I called back several times and the operator came on to tell me that the call could not be completed as dialed. They are just harassing people!!

You can no longer call this number back to follow the Do Not Call instructions.  You get the "cannot complete the call as dialed" message.

Get calls from this # several times a day.  ID's as wireless caller, but never leaves a message.

keeps calling!

has called 4-5 times... no message.... very annoying!

Got 2 calls from this number but no message; didn't answer since I don't know anyone in the DC area.

Called and hung up before I could answer it.  Did not leave a message.

Calls 3-4 times a day.  NEVER leaves a message, and if I answer without saying hello, they don't either.  As Ernie's comment reads "If they were a good caller..." they would at LEAST leave a message!

Thanks!  I registered in 2004, I just registered again.  I hope it stops..

Thanks, Hope that stops the calls.

All you have to do is call it back.  A message will instruct you to go on the NO CALL list. Very simple.
It takes 48 hours to activate.
thank you

Real pain due to several calls a week. I do not answer and they never leave a message. If it was a good caller they would leave a brief message at least once out of the last 25 calls!
