Telephone Options > Phone Application Options > Setting the "Go to Phone on Originate" Option

This option lets you change the "Go to Phone on Originate" selection. When you select "Yes," the Phone screen displays automatically whenever you place an outgoing call, for example, upon selecting a speed dial button to make a call. When set to "No," (the default) the screen does not change when you make a call -- but you can still manually select the Phone application tab.
