Called my home Sunday around 6pm EST.  No message left on machine.  I called number from caller ID back and got a recording saying I'd reached "the research dept", no specific company name though. Went on to say "if you're calling to take part in an opinion poll leave a message at the tone with your complete number"(I did not.) Must be some sort of opinion polling call center.

I have also received several calls from this number.  From Braintree - 1-781-884-0683.  I have not returned the call, and they do not leave a message.

On my caller ID it says "MASS MED STUDY".  I have not answered the call when it comes in and they've called more than once.

Got this call today called back and said it was a research. I am part of opt out why are they calling me?

I found this online

It's some survey company I guess....

unsolisited calls several times a week

I get a call from this number about twice a week.  I never answer it and they never leave a message.  Our number is unlisted.. and we don't get any telemarketers or anything.. so not sure who this is...

calls with no message

Called my home today.  No message left on machine.  I called number back got a recording saying I'd reached the research dept....talked about taking an opinion poll or some such thing.  Said to leave a message at the tone. Weird.
