CID shows Poolesville MD.  Called and does not leave a message.

Repeated calls from this number, daily and multiple daily as well.  Picked up the telephone and heard nothing but silence.  I suspect this is a "test call" to determine if someone is at home, to be followed up in short order by a second call from a different number, that second call being a scam, a telemarketer, a fraudulent "offer" such as a "free trip to the Bahamas" or something similar.

Silence, keep getting these kinds of calls, I rarely answer anymore.
