We too have received a number of these calls.  I am not returning any of them - just letting them ring through.

I got two calls in two days from (416) 210-3998.  I don't answer the call and let it go to voice.Woman left a msg saying she was looking for Tisha.  Her name was Hope and she left a number 1-(514) 865-7995 (in Quebec).  Her msg goes something like this:  Hi Tisha, it's Hope.  I have the stuff that you wanted for that lady sitting here.  Please call me back at 514-865-7995 so that you could pick it up for her... (or something like it)...  Smells funny since she wasn't specific about what she had for Tisha.  Always referred to it as stuff or thing...

I just got a call from 1-(416) 210-3998 @ 8:25pm 9/13/08...what the hell...it's weird i knew a few people in toronto but none by this number...very strange

Just letting these annoying calls ring through.  Wish someome would stop these annoyances - creepy, repeat callers!

Hi! I just received a call from this number, and the guy who sounded east indian, asked for me by name but I did not recognize him, so I lied and said I was not home and he asked when I would and I said around 10pm and he said well I really need to speak to her and I will call her then. This is so weird and my instinct tells me this is a scam, if he calls back I will try to get enough information to inform all of you. I will report him if this turns out to be a scam like I suspect.

This number is a Toronto payphone
