I once made a website where you could enter two phone numbers on. It would call A with B’s caller ID and B with A’s caller ID. After the call it would send an sms/call from the service explaining what happened and they could consent to release the recording for the pranker to listen to. It was funny to have Pizza Hutt and McDonald’s both think they’d called each other. Or two people standing right next to each other. I nearly got in quite a bit of trouble when someone pranked two high level people in the military, and they decided to have a conversation they probably shouldn’t have had on personal cell phones. It was fun while it lasted… but I wonder if something like this could work for spam calls. Basically instead of forwarding to voicemail, have it route to some pre recorded messages you make “yeah” “hello” “I didn’t hear that, can you say that again” and loud background noises playing. Then it can send you the recording as your “voicemail”. Could be fun.
