How can I upload a Ringtone on my Grandstream phone?

Linux Version:
Please use the Linux link provided as our phones will only use the format generated by our tools. How to use the tool is attached in the readme file. Be advised that only .wav files can be converted. If you have .mp3 files, they need to be converted to the .wav file format. You can find a free conversion tool online. The ringtone file can not be more than 100KB each. We suggest less than 70KB each. BT100 phone will only take two ring tone files and GXP2000 can take 3 ring tone files.

Windows Version:
Please use the Windows link provided HERE
. There are 8 steps to follow using the ringtone generator:

• Upload the ringtones to a computer.
• Save the file as a .wav file.
• Select the appropriate ringtone generator.
• Open the .exe file and then select (and double click) the ringtone file from your files.
• Click “generate ringtone file”. A .bin file will be created in the folder where the .wav file is located.
• Put the ring1/ring2/ring3.bin file under HTTP/TFTP server.
• Enter HTTP/TFTP server IP address in “Firmware Server Path” on Advanced Settings page of web UI.
• Click on UPDATE and REBOOT the device, just like how we do firmware upgrade.
• Then, the phone connects to the HTTP/TFTP server and grabs the ring tone file. After the phone downloads the file, the ringtone can be changed by using keypad or web UI. The config tool doesn’t support .mp3 files.
