Not sure if they ever were, but they surely aren't now. Even in terms of basic knowledge about DTMF.
When it comes to the details, I'm not sure how pressing buttons on a phone works nowadays. I think there's at least 3 different ways it can work with SIP. I would expect mobile phones to be just as bad.
