If it doesn’t what does it do?
If the phone has a bell, and the bell vibrates to produce a ring then it has rung.
If the phone doesn’t have a bell, then it alerts, notifies, signals, flashes, vibrates, etc… but does not ring a bell.
You know what, you’re right. And the act of putting in a number can’t be called ‘dialing’, because there isn’t a dial. Also, when a car stops at a designated spot and is shut down, that’s not ‘parking’ because there isn’t a park there like there used to be when that word was first used.
Language cannot possibly evolve in these obscene ways!
Is the sound I hear when I call you still a ring? If so, has your phone still rung?
In the purest sense of the word no, there is no ringer, there’s no bell
In the colloquial sense of the word sure, the phone has alerted you that there is a call
If your phone gets a call but doesn’t give you any indicator was their call at all? Probably
If you call for takeout, how can you be at home, silently? You’re not “calling” anything, nor taking anything out, as you’re squarely staying in.
Being that prescriptive would end up like an irl version of the Big Bang theory, just much much worse. (And the original is already… eh.)
Language for sounds doesnt work like that though. If I hear a pop song and say “dang that’s a great snare” it isn’t wrong if technically the sound is actually a synthesized snare. When you hear something you can name it without it having to be physically present. Plus plenty of things ring without being a bell.
