ROBO nuisance caller. No message.
Medical Alert Co. unrequested solicitation w/out message.

Called at 7:57pm on 5/3/2013, from number 856-200-8121.   Caller ID showed "USLIFECARE."    It was a live call, the message on myanswering machine went something like, "Hello, is anyboday there, hello?"   Then hung up.   No Idea why they called, but judging by the other posts on other sites, they peddle home warning or security services.   Checked their website, USLIFECARE.COM who Whois:

It's a GODADDY account set up in 9/2011.   They used Godaddy's now infamous "Domains by Proxy" service to hide their true identities.   As far as I can tell, the BBB has never rated them.  

I'm on the DNC, so if this was a telemarketing call, they were breaking the law.

All in all, looks like a pretty good bunch to avoid.

Thanks for researching the number for us BAS.   Definitely will avoid.

Wow!  Thanks for the info and all the time it must have taken to do this.

Got this call today at 12:57PM.  I just picked up/hung up w/o answering.  Knew it HAD to be spam by the "200" exchange.  There are not VALID exchanges with zeros in it.  Zeros are ALWAYS reserved for AREA CODES.
