The Music - phone numbers are
pronounced like poems.
Follow the music of the
pronunciation. Be careful about one thing. For "4895",
for example, English speakers always say,
"four-eight-nine-five" and NOT "forty-eight
ninety-five".
English speakers often say
the letter "oh" for the number "zero". When "oh" is
combined with some numbers, it is difficult to hear, for
example "oh-eight-oh". I recommend always saying "zero"
and "double zero".
