I don't know for sure, but I think that its a telemarketer. This isn't actually the number that they call you from, they use it as their call-ID.

This number is from FreePhoneLine.ca and appears when the FreePhoneLine number is called by a caller that is blocking their ID.

That is...

1) "Bill" has a FreePhoneLine.ca (FPL) number which he can forward to any other number in Canada (like his cell)
2) "Jane" calls Bill's FPL number but she decides to block her number so that he doesn't know what number she is calling from
3) Bill receives an incoming call on his cell and sees (416) 642-0882 on his call display

I didn't call back!

This is the number that shows up if I dial out from my Vonage phone using caller ID block (*67). Appears to be out of service if you call the number back.

They called me, asked for me by name, then said is was my pharmacy. They said they had my refill of Cialis and I just had to confirm it. I laughed at her, seeing as I'm 25 and have no need of boner pills.
You just have to say "Take my number off your list" and they have to comply.

I got 6 calls from this number today.  They claim to be Bell offering a new high speed internet package, first 3 months free.  It sounded real until they asked for my credit card number.  I said there was no way Bell asked for that information over the phone and I hung up.  They called back using private name and number but I didn't pick up.  

Watch out everyone!
