At 8 AM on April 17 2018 I got a call from (416) 343-7050. Message left was just some noise. When I called the number, I got the old "number is no longer in service"...That night at 1:09 AM I heard a bang on my door. I come out and there is a police officer standing at my door, his car in my driveway. He says "Do you have a problem with your phone?" I said "I don't know and I don't care, its 1 AM and I was sleeping". He said that he had a message on his "system" that I had a problem with my phone and because I can't call 911 he had to advise me of this. We got into an argument and I said to him that I didn't think it was necessary for him to be banging on my door in the middle of the night about my phone. Anyways it turned out that my phone was actually just fine.
Next day I called the police and gave them my story. They were able to check it and told me that someone called 911 from my number and than the call was disconnected. In those situations police are obligated to visit the residence to make sure that everything is OK.
My experience with (416) 343-7050 is similar to many other comments and that's why I posted it. It has to do with the police and 911 calls. Unfortunately the cops were unwilling to pursue this with me to try and figure this out so I think this will continue to happen.
I think its time that CRTC or the govt. or somebody got after Bell and Rogers and got them to properly police their networks.
It should not be possible for anyone to call from a number "that is no longer in service"!? This nuisance that millions of customers have to endure should end. Of course Bell and Rogers have really no incentive to fix this. Not only it would cost them money but also they would not be making as much money from selling unlisted numbers and call display services. Corporate greed wins again and consumers lose. Its a disgrace.

Just got a call from this number around 2am!
When I try to call back the call doesn't go through

Its Toronto Police Parking Enforcement. Typically they only call you when they have arrived at your place because you have placed a call to them for some parking infraction on your property.
The reason they dont answer if you call back is because you need to go through switch board. This number does not accept incoming calls.

I just received a call from this number, but I did not pick it up.
I have a Mobilicity phone and it shows that I made an Emergency call using 112, which is doubtful since my phone was in my pocket and turned off.
I tried calling the number back, and received message "wireless number is unavailable at this time, please try again later"...

I just got call from (416) 343-7050 , i tried calling back but getting busy signal , call doesn't go anywhere.

Now it makes sense, same thing happened to me.  On my call log, it said that I did make an emergency call.  I have a blackberry, and when it is locked, and a key is pressed, there is an option to make an emergency call.  I guess enough keys were pressed, by accident, to make that emergency call.

I'm not sure if this applies to other cell phones.

Toronto Police Service.
The Emergency Call button on the blackberry triggers it. The phone may come unlocked and accidentally dial it. It has happened a few times to me. The people on the other line are very nice tho.
Always felt embarrassed while talking to them.

Same thing happened to me...if you ask me it is Police:Surveillance and Patrol not Police:Serve and Protect.

I think at this point the cops are phishing. If you ever knew a big dealer or some sketch bag thief and had called them...or perhaps even if you had a plumber you had called but he dabbles in weapons dealing, which you had no clue about.... well then maybe the cops are calling phones in that network and listening in for a few minutes to see if you reveal something incriminating about yourself.

n.b. this is only a theory and only to be considered paranoid if it was proven to be a useless waste of time for the cops. Maybe it is actually effective.

impossible to say unless you were a cop and if you were...would you say?

the reason i think this is because the cop who talked to me started giving me the third degree about the convo they had listened in on. it made me very uncomfortable to be treated like a scab of society when i'm just sitting in my buddy's car talking about a ring he has to pawn because a contractor still hasn't paid him for a tiling job he did six weeks ago.

democracy:checks and balances...we clearly need some more of those.

Same [***] different day

This is an outbound line from the Toronto Police 911 Communications Centre. They will call you from this phone # when your phone dials 911 and no one is on the line. Could be an accident from having your phone in your pocket, or from giving your child the phone to play with. Some phones will not show you placed a 911 call in your log if it is activated by your touch screen and not by dialing the numbers yourself. All they are doing is calling you back to make sure there is no real emergency, just let them know you dialed in error.
