I finally got sick of the phone ringing at all hours with no message and answered it.  They ask "is this a business or a residence?".  after my rude question, she said "we are contracted by the Federal Health Department to determine and seperate out business phone numbers from residence phone numbers".  I answered (rudely again), and was hung up on immediatly. I have been on the "do not call list" for over a year now - but certainly not the 5 year limit yet! hope they stop now.

I got calls from this # 2 days in a row.  I answered on the second day and a woman stated that she was calling in preparation for a study and asked if she had reached a business or household.  When I told her it was a household she said "thank you, have a good day" and hung up.

Received one of these today, claimed was calling in preparation for a Department of Transportation study.  Also asked if this was a home or business.  Lady calling got huffy and said never mind when I asked why she wanted to know.  Did a *69 to get the number.  Not surprised it is a scam.  It is a shame that there are people willing to stoop to such measures just to make a dollar.

Called on Sunday 1:50 in the afternoon, no one answered

Just got another call from this number, this time I answered and got the line about seeing if it was a residence or business.  I called the number back about 10 minutes later, and got a vm with a female's voice asking for my name and number and that she would call back.  Who are these people?  This is the 3rd night in a row that this number has appeared, but they don't leave a message.

I have caller ID and I'm on the do not call list. I only answer if I have the time to bust some telemarketers balls. They did not hang up, just listened.  No problem, it's just a waste of their time.  I always report anyone who is in violation, so no one will ever get a dime outta me and if they give my name as a lead that caller will be reported.

I've gotten several of them each day for about a week now, too (and now on the weekend). I'm on the "do not call" list. If they really want to know if we're a business or a residence, all they need to do is listen to my voice mail message. It's pretty annoying - waste of a lot of my time. I wish we could charge back something to them for using the phone line I'm paying for.

These people are constantly calling.  When you answer the phone there is no one there.  They will never leave a message on my anwering machine.

This number rings and nobody answers, after you say hello. This is on a sunday at 12:30PM

These callers are trying to drum up lead lists and validating the numbers to see if they are still active.  It is a scam to beat the DoNotCallRegistry by having no one speak to you, you cannot really complain it was an unsolicted sales call.  Yet they are compiling the number lists for marketing and survey leads which they sell.  Call block them if you have the service to prevent your number from being added to numerous lists.

Have had this number call me several, several times...EVERY time I answer and then they just hang up----NO ONE IS EVER THERE....have been on do not call list for a while now....

I am really getting tired of the phone ringing and nobody answers, after you say hello.

I've been getting hammered by these roaches every day for about 5 days now, including Sunday.

We having been getting daily calls from 410-347-5600.  I have reported them to the "do not call" web-site.  When answered, the line is open, but no on responds.  When allowed to go to answering machine, no message is left.  The number is for C. R. Dynamics.

I got a call also from CR Dynamics at the listed phone number on my caller id.  THey just hung up after a bunch of clicking...not talking.  I called the main number and got a similar response.  THey generally call 3-4 times a day.

I just got a phone call from this number.  I don't recall seeing it on caller ID before. When I answered, I said "Hello" three times and no one said anything.  I finally hung up and then called the number back.  A man answered the phone saying "CR Dynamics may I help you?"  I explained that I just received a call from that number and did not want to be contacted again.  He asked for my phone number--I hesitated at first but thought surely there was some way he could find out--and told him.  I asked what kind of company his was and he said it was a research company.  I told him again not to call.

this call was recorded on my voice mail for my house phone.
Whispering threats is the best I could understand. I am not to try to contact them back in any manor or something will happen to me. Most of the the whispering is not easy to make out. Wish there was a way to put the recording on the internet, so everyone can hear it.
saved it in my voice mail, hoping to get help to make the rest of recording figured out. I wanna get the ***** who did it.
anyone else get one like this?

I have a unlisted number and I am getting muti phone calls from thisnumber everyday.  They are unwanted and need to be taken off the list.  My number is 3366703788

I am getting calls from this number every day for the past few weeks.

Caller said "I'm calling from a survey company and I want to axe you one question Is this a home phone?" I said yes and hung-up. I'm going to try the ### next time though.

Bottom line, if you did not solicit the call, no mater if it's a survey, a telemarketer, or someone giving out free ice cream cones, they should be FINED and/or jailed for continuing. We receive a call EVERY DAY from these shmucks. In the past we asked to be removed, the immediately hang up. SO it should not matter if they are using the loophole of a  "survey" to call you.
The really want to sell you something.
Let;s see a surver, do you want to lower your credit card rate? You say yes, then the low lifes try to sell you a service.

I have made a formal complaint to the FCC and the NO call registry, I suggest you all do the sale, each time you get the call.

i m on the no call list.  too many incoming calls.  please help.  thank you

several calls to our home # not wanted.

couldn't locate me on the list wasn't sure if it was home or business phone

Received a call twice today.  CR Dynamics - 410-347-5600.  We too are on the do not call list. They got our machine and left no message. I filed a complaint today.  Everyone must do so!

410-347-5600

call at all hours and hang up...

claimed to be public research survey

No message left, but they've been calling persistently for about a week now. Not sure if they're calling multiple times a day or not, but I have received calls both in the morning and evening.

Received numerous calls from this phone number - surprising because we are on the National "Do Not Call List". No message left. Time to tunr them in - "CR Dynamics" in Balti-Moron. Enough is Enough!
