18.6.10 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 291).
• You can also configure the Call Waiting table using the ini file table
parameter CallWaitingPerPort (see 'Configuration Parameters Reference'
on page 541).
• For additional call waiting configuration, see the following parameters:
FirstCallWaitingToneID (in the CPT file), TimeBeforeWaitingIndication,
WaitingBeepDuration, TimeBetweenWaitingIndications, and
NumberOfWaitingIndications.
To configure Call Waiting:
1. Open the Call Waiting page (Configuration tab > VoIP menu > GW and IP to IP
submenu > Analog Gateway submenu > Call Waiting).
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 291).
3. Click Submit to apply your changes.
4. To save the changes to flash memory, see 'Saving Configuration' on page 482.
