Voice Call Confirmation

A simple issue. I have my phone out, have been texting a friend. Suddenly, while I'm not looking, I hear the fateful noise. My friend is pissed, he doesn't want to call, and neither did I! So let me ask, why is there no option for a call confirmation on mobile? It's simple really. Unlike desktop, it's much easier to accidentally press it, and if you dare be in a group chat, you've just called several people on accident. Please, for the love of god, just add this simple feature.
