I agree that its upsetting too, I am annoyed by these calls just as much as you.
Its great that you created an algorithm to reduce the calls. You seem very knowledgeable in this field, perhaps you should work for Rogers Wireless, you could easily make change happen in the company.
These decisions usually come from higher up in the company, so if you really have the knowledge to stop spoofing and annoying spam calls, you should do some networking and make friends and contacts with some people in the company who have some pull. maybe they will like your idea?
Just as an FYI, as discussed in post 17 of this thread, Stir/Shaken will become active by the end of this year, if not earlier. This should reduce the number of spam/scam calls significantly. Link below:
The reason I'm not sure of the date this will be implemented by Rogers is because I'm not sure if they'll meet the September 30th 2020 date "expected" in the implementation recommendations of the link above.
