has called everyday for the last several weeks. Finally called them back - recording states they are hired by museums, and other companies for renewing membership - leave your name and phone number to be removed.
Doesn't work.
I have reported them to FCC.

this number called every morning. I didn't  answer.

Calling for weeks on cellphone even though have registered on Do Not Call. My associate is going to file an official complaint.

Left no message. 8 others have reported it as spam on Mr. Number app for Droid phones.

Came back to my desk and saw the voice mail light on my phone (work) and a missed call on my personal cell phone. Same number 877-683-1527. The voice mail was dead air but I could hear someone was on the other end. Then my husband sent me a text and said that there were 44 missed calls on the home phone! How do we get rid of pests like this??

Has been calling daily for the past few weeks, usually when I pick up there is no answer or automated recording. Today an actual human was on the line and was a paid caller for the American Chemical Society trying to get me to renew my membership. I am not sure if he was working for the ACS or if he was part of a separate company contracted by the ACS to harass people about renewing lapsed memberships.

I had the same 'breather'.  this caller has called more than 25 times

Caller calls my place of employment every day, never leaves a message, Called the number back and left voicemail to stop calling this business line.  Calls stopped for about 2 days, started again today.

11 calls since the first of the year, but 7 within the last 2 weeks.  If you pick up, no one responds.  Messages left only give the last few words. Must be a hoax.

This number, 877-683-1527, has called repeated times over past month. No idea who they are. They don't leave a message and don't answer when phone is picked up. Stopped answering phone. Screening calls and noting how often they are calling. Next complaint is going to the FCC. STOP!!!

Called me, and I answered (thought it was another company.) I get an automated voice saying, "Hello, I have a call for you." Then nothing but white noise. Freaky.... Don't answer!

calls me every morning and then hangs up

was called, no voicemail left.  called the numberback.  voice message says this number is a marketing group calling to renew a membership.  I haven't cancelled any memberships recently, so i have no idea what this is in regards to.  

Got one today 2/24/14...  no message left.

Called me today & left no message, but they did not hang up immediately and some sounds at the call's place of origin (likely a call center) were recorded.  I could hear the caller breathing in the background as well as some office chatter.  As indicated above by Mike, the caller ID just says "Toll Free Call."  Definitely not important.

877-683-1527 is calling for some unknown reason.  Please block this number.

Same thing -- two calls this week.  I did not answer, called left no message.  Suspicious.
