Go to the CCM Administration page. Choose Device > Device Settings > Phone Button Template.
Click the Find button.Click Standard 796x, say 7965.
Click the Copy button and rename the new template as 7965 with 7914.
From the Feature column, choose Speed Dial for the buttons that you want to configure as speed dial. On the Label column, enter the label to be displayed on the module for that button. (If you do not want a label, leave this blank.)
Go to Device > Phone, and search for the phone that has the 7914 installed and click on the same.
Under the Phone Button Template Information section, choose the newly created 7965 with 7914 button template.
