SIP User's Manual A. Configuration Parameters Reference
A.12.5.2 Call Waiting Parameters
The call waiting parameters are described in the table below.
Table A-42: Call Waiting Parameters
Parameter Description
Web/EMS: Enable Call Waiting
[EnableCallWaiting]
Determines whether Call Waiting is enabled.
 [0] Disable = Disable the Call Waiting service.
 [1] Enable = Enable the Call Waiting service (default).
Digital interfaces: If enabled and the device initiates a Tel-to-IP
call to a destination that is busy, it plays a Call Waiting Ringback
tone to the caller. The tone is played only if the destination returns
a 182 "Queued" SIP response.
FXS interfaces: If enabled, when an FXS interface receives a call
on a busy endpoint, it responds with a 182 response (and not with
a 486 busy). The device plays a call waiting indication signal. When
hook-flash is detected, the device switches to the waiting call. The
device that initiated the waiting call plays a Call Waiting Ringback
tone to the calling party after a 182 response is received.
Notes:
 The device's Call Progress Tones (CPT) file must include a Call
Waiting Ringback tone (caller side) and a Call Waiting tone
(called side, FXS only).
 FXS interfaces: The EnableHold parameter must be enabled
on both the calling and the called side.
 Analog interfaces: You can use the parameter table
CallWaitingPerPort to enable Call Waiting per port.
 Analog interfaces: For information on the Call Waiting feature,
see Call Waiting on page 300.
EMS: Send 180 For Call
Waiting
[Send180ForCallWaiting]
Determines the SIP response code for indicating Call Waiting.
 [0] = Use 182 Queued response to indicate call waiting
(default).
 [1] = Use 180 Ringing response to indicate call waiting.

When the FXS device receives a call on a busy
endpoint (port), it responds with a SIP 182 response
(and not with a 486 busy). The device plays a call
waiting indication signal. When hook-flash is detected,
the device switches to the waiting call. The device that
