Configuring Call Waiting

The Call Waiting table lets you enable call waiting per FXS port. When call waiting is enabled for a port and the device receives a call for the port, if the port is busy (i.e., currently in another call):

1. The device responds to the caller with a SIP 182 response (instead of a 486 busy).
2. The device plays a call waiting indication signal to the busy port.
3. When the device detects a hook-flash from the port, the device switches to the waiting call.
4. The device plays a call waiting ringback tone to the calling party after a 182 response is received.
● For ports that are not configured in the table, call waiting is according to the global parameter, as described in Enabling Call Waiting.
● In the installed CPT file, you must include the "Call Waiting Ringback" (#17) tone (heard by the calling party) and "Call Waiting" (#9) tone (heard by the called party, for FXS interfaces only). For more information, see Call Progress Tones File.
● For call waiting support, you must enable call hold for the calling and called parties, as described in Enabling Call Waiting.
● For additional call waiting configuration, see Enabling Call Waiting.

The following procedure describes how to configure call waiting per port through the Web interface. You can also configure it through ini file [CallWaitingPerPort] or CLI (configure voip > gateway analog call-waiting).

1. Open the Call Waiting table (Setup menu > Signaling & Media tab > Gateway folder > Analog Gateway > Call Waiting).
