I just received a call from Global Group Travel..  same type of message as above comments with the recording etc...  This time it said I was selected to win $999 towards a trip based on a recent trip I took with Air Canada.  After answering a qualifying question they passed to me to a third person that asked for my name.  I told her I would like to learn more before disclosing my name and she hung up.  This is an obvious scam so posting to just keep consumers aware and alert.  The number was (416) 917-8100.  

89xxxx

Got A Call with No message and told out of service when called back

Just got a call from same number and missed the call I went to look where this phone number comes from and found you all.

On July 9 got a call from this number, I refused to answer as the number was strange to me and looked like a scam.

They called themselves "Global Group Travel", but as soon as I asked them to confirm this, they hung up.  It's obvious they know they'd be charged with a $10,000 fine for calling while on the DNC list.I've not bothered to check, but I'm sure you'd find that no such company exists.  They will likely be a numbered entity.  Their number is owned by Bell, and for the person asking why you can't call them back, it's because they've chosen to let you see "(403) 912-8989" but that's not the number associated with the SIP they're using to dial you from.They're using IP telephony, and it does make it more difficult to figure out who they are and how to get them charged.  Anyway, obvious scam.
