Appears to be a call center of some sort?  On the vcm, i only heard someone say "hello", in the background you can hear call center-type noise.

Spammer?  Don't know, but I'm guessing if it was a legit call -- there'd be more info.

Missed call, they did not leave a voice mail.

Same here about 10 times in the last 10 days all at 7:15pm
