Who called from 3018842399

Definitely using a an auto-dialer, there were several seconds of silence between answering the call and actually getting a voice.  Some sort of veterans group.  It probably was a recording since it didn't stop right away when I spoke to say this was a wireless number, then I hung up.

No one answered when I said "hello."

Robo-Dialer, it rang 4 times and hung up, they left no message. Caller ID just shows "MECHANICSVL  MD"

CID said "Unknown name".  Called at 5:30 PM to my land-line.  I didn't pick up; they left no message.

My caller id said "Maryland Call".  Guess it wasn't important, or else the caller would have left a message.
