Explanation:
Phone Button Template Configuration
Cisco CallManager includes several default phone button templates. When adding phones, you can assign one of these templates to the phones or create a new template. Creating and using templates provides a fast way to assign a common button configuration to a large number of phones. For example, if users in Certkiller do not use the conference feature, you can create a template that reassigns this button to a different feature, such as speed dial.
Make sure all phones have at least one line assigned. Normally, this is button 1. You can assign additional lines to a phone, depending on the Cisco IP phone model. Phones also generally have several features, such as speed dial and call forward, assigned to the remaining buttons.
Step 1 Choose Device > Phone Button Template.
Step 2 Choose a template and click Copy to create a new template. The new template exactly duplicates the existing template and automatically assigns it a new name. You must update this new template if you want it to differ from the original.
Step 3 Update the appropriate settings.
Step 4 Click Insert to add the new template.
Step 5 Click View Button Layout to verify the button layout. Not C: The Phone Button Template menu is found under Device > Device Settings
