Music file, including phone ringtone file and call hold music file, is a binary file and can be
updated to a phone. Phone ringtone file is stored in page2-page4 and call hold file in
page5-page7, each part is 192K(3×64K ).
Tone is sampled at 8k points per second and compressed by 8-bit mu law with 1 Byte per
sample point. We set 32768 Bytes (32K) as a section and use 32640Bytes of them; the
last 128Bytes are not used. So, 4.08 seconds music can be stored in one section. The
size of a music file is 196608Bytes (6×32768Bytes) and the music stored in it can plays 6
×4.08=24.48 seconds.
Warning：
