I would absolutely HATE HATE HATE such a feature, if it were available for someone to call my phone number over and over and over. If someone calls me and I don't answer or return their call, it means I don't want to speak with them. I most assuredly would be upset if they could spam my phone with calls over and over and over.
I pray this feature never exists. LIKE EVER!
Of course should such a feature come to be, I'd immediately block the number, and I'm sure others would too, so not sure this feature would help you with whatever reason you had to call someone 80 times to begin with.
