Received a couple calls from this number. Upon calling number back, got silence (tested twice). Not sure if they're 'scammers' but they are not friends, business associates, contacts, etc. known to us...so annoying.
(perhaps the definition of a scammer?) ;)
same 3/6/2013 - silent when answered
This number kept calling over the past couple of months. Silence when calls were answered. Assumed this is another telemarketing call.
