Call Waiting

The Call Waiting feature enables FXS devices to accept an additional (second) call on
busy endpoints. If an incoming IP call is designated to a busy port, the called party hears a
call waiting tone (several configurable short beeps) and (for Bellcore and ETSI Caller IDs)
can view the Caller ID string of the incoming call. The calling party hears a call waiting
ringback tone. The called party can accept the new call using hook-flash, and can toggle
between the two calls.
To enable call waiting:
1.
Set the parameter EnableCallWaiting to 1.
2.
Set the parameter EnableHold to 1.
3.
Define the Call Waiting indication and call waiting ringback tones in the Call Progress
Tones file. You can define up to four call waiting indication tones (refer to the
FirstCallWaitingToneID parameter).
4.
To configure the call waiting indication tone cadence, modify the following parameters:
NumberOfWaitingIndications,
TimeBetweenWaitingIndications.
5.
To configure a delay interval before a Call Waiting Indication is played to the currently
busy port, use the parameter TimeBeforeWaitingIndication. This enables the caller to
hang up before disturbing the called party with Call Waiting Indications. Applicable
only to FXS modules.
Both the calling and called sides are supported by FXS interfaces; FXO interfaces support
only the calling side.
