I received a couple calls from this number, one after the other, but I didn't answer.

On my display, it showed sialk.ca

Just got a call from 200-9 (no area code, just that number in the info part plus "unknown" of course). I answered, no reply, they hung up. This was on 4/10/14 at 2:53pm

I've gotten a few calls from some Indian a**hole (named "Gary" would you believe).  The scam was he wanted to give me a cheap mortgage and all I had to do was give him all my banking info, SIN # and so on.  The first time my wife answered she laughed and told him to suck eggs.  I wasn't as nice.  I'm listed with the CRTC no call list, so I rarely get calls now but this is different...some sort of scammer.  Time to start answering with the air horn again.  Maybe if he's deaf, he won't be able to call cause he can't hear the replies.

I just received two calls from this number. The person sounded like he was far away and he also sounded foreign and I couldn't make out what he was saying.

Yup, I just got a call from a heavy accented man...caller ID = Spider Spider and he claimed he was from Bell Mobility.  He sounded like he was calling from a cell phone, on the highway, with his windows down.  It was so noisey.
I just said I wasn't interested and hung up.  He is not from the GTA area...no way!
