Call waiting allows a user who is already on a call to be made aware of another call to their extension. The user hears a call waiting tone and depending on the phone type, information about the new caller may be displayed. The call waiting tone varies according to locale.
Call waiting is primarily a feature for analog extension users. For Avaya digit phone with multiple call appearance buttons, call waiting settings are ignored as additional calls are indicated on any free call appearance button.
To answer a call waiting, either end the current call or put the current call on hold, and then answer the new call. Hold can then be used to move between the calls.
Call waiting for a user can be enabled through the IP Office configuration (User | Telephony | Call Waiting On), through the Phone Manager application and through programmable phone buttons.
Call waiting can also be controlled using short codes. The following default short codes are available when using Call Waiting.
*15 - Call Waiting On
Enables call waiting for the user.
*16 - Call Waiting Off
Disables call waiting for the user.
*26 - Clear Call and Answer Call Waiting
Clear the current call and pick up the waiting call.

Call waiting can also be provided for hunt group calls (Hunt Group | Hunt Group | Call Waiting On). The hunt group type must be Group and all the group members must have their own call waiting setting switched on.
