Appendix B: Tones
Tones are audible signals of various frequencies that give information about the status of calls and features. While using the
Coral system, many different tones will be heard. These tones may vary for different locations, as each system is customized
during installation. While the sounds of the tones themselves are not described, their general use is discussed below. In order
to familiarize yourself with these tones, try accessing various features and listen to the resultant tone signals. The most
frequently heard tones are:
