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. |
| ● | The feature is applicable only to FXS interfaces. |
| ● | 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).
| ➢ | To enable call waiting per port: |
| 1. | Open the Call Waiting table (Setup menu > Signaling & Media tab > Gateway folder > Analog Gateway > Call Waiting). |
| 2. | Select the row corresponding to the port that you want to configure, and then click Edit; the following dialog box appears: |
| 3. | Configure call waiting per port according to the parameters described in the table below. |
