Caller has called numerous times and hung up on me.

called, stayed on the line, then hung up,

I've gotten two of these calls - super annoying!!!  I did not answer and they didn't leave a message.  I'm going to try and block these but I'm not sure if I can. I called them back and they hung up on me - twice!

Long blank message left on my answering machine. Could hear some background noise and shuffling sounds. I swear I thought I heard someone burp in the background. Very annoying! Supposedly a Bell land line phone in the Ontario area.

got a call from this one today, missed it tryed to call back but no answer.  I think it is an outgoing telemarketer line
