Tones and Their Meanings
As you become more familiar with your IP Telephone, you will recognize the various tones you hear in response to an
incoming call or while using the handset. The chart below provides an overview of the tones you hear; check with your System
Administrator to verify if the descriptions are accurate for your system. Ringing Tones accompany an incoming call. Feedback
Tones are those which you hear through the handset (receiver) or the speaker.
Note: The PBX, not the telephone, generates these tones, which may be different than the list below. This difference is
especially true when the PBX is outside of the United States.
