got a call on my work phone from 720-452-5525.  'they' left no vm.  caller id says "CONTACT CENTER" in all-caps.

Another magazine telemarketing call from Ebsco Magazines  "Electronic Design" magazine

Answered call and caller immediately hung up.  Caller ID displayed Contact Center from Denver CO.  Blocked number.  Agree with ladygeek that this was an automated call and add that it is also harassment.  Have always told telemarketers to put me on their do not call lists and don't ever contact me again.  Don't know if that is related here.  Have had a number of these types of calls lately.  Too bad, the feds don't care about policing these criminals.  They should.  People have a right to be free from harassment.

Listed on caller id as 'Call Center'. No answer.

I got this call and was told it was modern salon (I'm a hairdresser) they wanted to renew my subscription.
