One that answers, GP isn't fighting 1980's phreakers with a bluebox, they are using Twilio, Signalwire, etc to make automated verification calls/sms for a very large company as far as I understood it. The call being answered is baked entirely into your programmatic logic. Unless I'm missing some niche telco semantics or lingo here? Or they are rolling their own? To embrace the "don't question it, you don't understand" narrative, I'm actually quite stunned someone would let this go on for such a long time, if this is corruption, crime or some other sort of telecom fraud aided and abetted by foreign governments/companies why not just turn off the tap and ban the country code if it was such a cost sink? Why not use some of the many alternative (and significantly more secure) verification methods for your customers?
