Here is how to customize Toku Connect ringtone.
On your Toku Connect application, you will need to go to settings on the top left "≡".
You will go to "Settings"
Once done, you will see "Advanced" option. Once there, you would need to scroll to the middle section and you notice "Notification, Audio & Visual Effects".
Below is for your reference.
Go to "Ringtone Type" and it will have 3 options. Select "System default" will set the ringtone according to your mobile ringtone. Else, if you prefer custom, that would be the third option.
You can now set your favorite ringtone!
