We received a call from 905-346-3495 which we had programmed our phone to block. 30 seconds later, we got a call from this number (416-900-1140). It might be a coincidence, or it might be the same caller just using a different phone number alias. I've now programmed our phone to block this number as well. No idea who is calling, but if they don't leave a message, they get blocked.
