Call on my cell phone. I only answered because I know people in the area code. Picked up and a voice (sounded computer generated) said hello. Then there was dead air. Possibly a new spam caller or new spoofed number trying to verify my phone number as belonging to a real person. Have blocked the number. Caller ID just said "Maryland".
Just called my cell phone on May 22nd 2016 at 1:30 PM and phone only displayed the number. Since no VM was left, the call wasn't important to begin with. Number is now blocked permanently.
This number, without a Caller ID Name, called one of my mobile lines the afternoon of May 22, 2016. I didn't answer, and the caller didn't leave a message or call back. Upon finding other recent reports here of nuisance calls from this number, I'm perfectly comfortable adding it to my blocklist.
