This is how call privacy works with Bell.  They are the only provider that has this feature.Block all incoming calls from unknown callers.Key benefitsEvery caller must enter a number before their call goes through. Glance at your display screen and decide whether to take the call. Set a 3-digit passcode to let those you know get through quickly. Create a Call Screen list to block up to 12 numbers; add, change or delete them as necessary.

If you do not have call block on your phone go get one.  They can't bother you if you block their number!

Got a call from this number @ 4:153 p.m..  Didn't answer it.  They left no message.  I'm on a "do not call" list too.  My telemarketer calls have been reduced considerably, but I still get occasional ones.

Unknown number. Frequent calls received from this number. Sound fishy, must be a scam.

Called here yesterday, no voice mail.  Spam, scam or telemarketer.

I have "block" on my phone - it still rings once and then is blocked.. which when someone is calling every hour of the night is still a big problem. I have called Bell and subscribed to "privacy" screen.. only to find it doesnt work for long distance numbers, 1-800 numbers, unknown numbers and best yet.. cell phones which many of these seem to be.. all that to say - that form of blocking also doesnt work.. Im also on the "no call" registry.. but of course that doesnt work if the call is originating outside of Canada.. if from within Canada - at least you can put in a complaint to CRTC at 1-+1 866-580-3625.
