Depending on your phone provider you can activate a feature that challenges the caller to solve a small problem before connecting the call.
TELUS calls it “Call Control”, and all its subsidiaries offer it. The major phone providers offer it too. It is the only thing I miss from my old TELUS plan.
- hanklazard 4y agoInteresting solution! I’ve never heard of this but it makes sense, like a captcha for phone calls. I’m in the US and have had to stop answering my phone thanks to 2-3 spam calls per day. The real answer is for the phone companies to use a protocol that doesn’t allow easy spoofing of any phone number (I believe one has been proposed but not adopted). Hilariously, I even have a medical provider app called Doximity that abuses this network ‘feature’ to disguise a doctor’s personal cell phone as the phone number of their medical clinic.
