Viewing Average Call Duration

You can view the number of established calls over a 15-minute interval and the average call duration (ACD) in the Web interface's Average Call Duration page. You can filter display by a specific SRD or IP Group. The page displays the following two graphs:

■

Upper graph: Displays the number of established calls (INVITEs) in a 15-minute interval. The x-axis indicates the time (hh:mm:ss) of the call and the y-axis the number of calls. The graph is refreshed every 15 minutes.

■

Lower graph: Displays the ACD. The x-axis indicates the time (hh:mm:ss) and the y-axis the average call duration. The ACD is refreshed every 15 minutes and therefore, this value reflects the average duration of all established calls made within a 15-minute interval.

➢

To view number of active calls and average call duration:

1.

Open the Average Call Duration page (Monitor menu > Monitor tab > Performance Monitoring folder > Average Call Duration).

2.

From the 'SRD / IP Group' drop-down list, select the configuration entity (SRD or IP Group).

3.

From the 'Index' drop-down list, select the specific SRD or IP Group index.

Use the Zoom In button to increase the displayed time resolution or the Zoom Out button to decrease it. Instead of using these buttons, you can use the slide ruler. As you increase the resolution, more data is displayed on the graph. The minimum resolution is about 30 seconds; the maximum resolution is about an hour.

To pause the graph, click the Pause button; click Play to resume.
