SIP User's Manual 3. Web-Based Management
3.3.2.8.5.10 Configuring Call Waiting
The 'Call Waiting' page allows you to enable or disable call waiting per device FXS port.
Notes:
• This page is applicable only to FXS interfaces.
• Instead of using this page, you can enable or disable call waiting for all
the device's ports, using the global call waiting parameter 'Enable Call
Waiting' (see ''Configuring Supplementary Services'' on page 148).
• You can also configure the Call Waiting table using the ini file table
parameter CallWaitingPerPort (see SIP Configuration Parameters).
• For additional call waiting configuration, see the following parameters:
FirstCallWaitingToneID (in the CPT file), TimeBeforeWaitingIndication,
WaitingBeepDuration, TimeBetweenWaitingIndications, and
NumberOfWaitingIndications.
¾ To configure Call Waiting:
1. Open the 'Caller Waiting' page (Configuration tab > VoIP menu > GW and IP to IP
submenu > Analog Gateway submenu > Call Waiting).
Figure 3-100: Call Waiting Page
2. From the 'Call Waiting Configuration' drop-down list corresponding to the port you
want to configure for call waiting, select one of the following options:
• 'Enable': Enables call waiting for the specific port. When the device receives a
call on a busy endpoint (port), it responds with a 182 response (not with a 486
busy). The device plays a call waiting indication signal. When hook-flash is
detected by the device, 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.
• 'Disable': No call waiting for the specific port.
• Empty: Call waiting is determined according to the global parameter 'Enable Call
Waiting' (described in ''Configuring Supplementary Services'' on page 148).
3. Click the Submit button to save your changes.
4. To save the changes to flash memory, see ''Saving Configuration'' on page 169.
