Ring types
Handset ring types (soft, normal, vibrate, etc.) are programmed by the
handset user and are not accessible or changeable by the system
switch. Whenever possible the audible ringer on the handset will
follow the cadence provided by the system switch. Call progress tones
provided by the host system will be passed through to the handset.
