Weird one,caller id says Pots Phone PQ as another poster states

Received call from this number today and when answered, caller immediately disconnected.

This number called my landline for the first known time today. I was on the line with another call, at the time, and did not flash over to the (819) 790-3651 caller.  No message was left on my answering machine.The index of area codes in my phone book indicates 819 numbers are in Quebec, Canada.

rang twice and hung up befor i could answer it.

Called and left no message as usual.
