"Phone" was not accepted, so I reported it; but I don't know anybody who uses the word "telephone" any more; it's become quite rare! (In Usono, anyway...) Does anyone find the word "telephone" in current use? It's certainly clear, and I still use it once in a long while, but it's a sign of belonging to an older generation, heh!
Maybe because "phone" is usually "mobile phone" = poŝtelefono. Not a telephone at home or in the street
