Ringtone File Size
File requirements for ring tone conversion:
1. Must be either .wav or .mp3 format [recommend .wav format]
2. Converted file size must be less than 64KB other wise it will override next file slot space.
3. Flash only has space to store 3 ringtone files (64KB x 3 = 192KB total space)
The ring tone generator supports 16-bit linear PCM as input (not PCMU or PCMA).
If a ring tone file is larger than 64KB, it will occupy the next available ring tone file slot. For example: If
the 2nd ringtone file size is more than 64KB (but less than 128KB), the 3rd “ring3.bin” will not have
enough storage space and it will not be able to load into the phone.
The ringtone files must follow the following naming convention: “ring1.bin”, “ring2.bin”, and “ring3.bin”.
Ringtone files can not be renamed.
