I want to install a captcha/menu into my phone (like "press 1 to speak to the owner of this phone") but my phone doesn't allow my software to interact with my phone calls. I can't even record them!
I don't remember the last time I had a spam call make it past it. They almost always just disconnect.
You’d have to disable inbound POTS though.
Why would that be? POTS calls are gated to VoIP above the end-users system.
