Each key on your phone sends a different tone. It's sometimes hard to hear the difference with a human ear, but there are different "tones" for all 12 keys on your phone. The computer recognizes the tone.

It would not hardship me. it style of feels a small fee to pay to maintain from unnecessarily inconveniencing audio equipment of different languages. that is less difficult than the only option which could be for companies to have a separate telephone huge style for each diverse language. As English is the dominant language interior the U.

I additionally agree that anybody residing interior the U.

Each key sends two tones at once. Do a search for "d.t.m.f." or "tone dialing" on Google or look in Wikipedia.
