CUSTOMIZED RING TONES
Download the free ring tone generation software @ http://www.grandstream.com/y-ringtone.htm. Please
follow the same rules as Screensaver Images
to generate the ring tone files and load them into the
phone.
Ring-tone File Size
Files 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 overwrite next file space.
3. Only have flash space to store 3 ring tone 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 ring tone 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 ring tone files must follow the following naming convention: “ring1.bin”, “ring2.bin”, and “ring3.bin”.
Ring tone files can not be renamed.
