When the Phone window is open, you can simply start typing a telephone number on your keyboard. Navigate UC PC Client will understand that you want to make a call and switch to the Make Call screen.
The Phone window allows you to interact with the current call in a number of ways.
One of the most common ways is to click the “New contact” or “Show contact” button to add a new name or to view the current caller’s details in the shared Address Book.
Users can also click any buttons showing integrated application names to open the caller's record in those applications.

When a call is ringing, you can choose to answer the call by clicking the "Answer" button or deflecting it (transfer it without answering it) to another extension. Deflecting a call is done in a manner similar to transferring calls. If you are already on the phone and someone else calls you, then you can use deflect productively to move the call to a co-worker.
It is also common to use this screen to perform a transfer of the current call to another extension or user. To do this you must be connected to the call (as opposed to it being on hold or ringing). To transfer a call you do NOT press the Hold button - it has a different purpose (more about his later). Instead you either press the Announce button or the Transfer button. You choose the button according to whether you want to speak to the other person (Announce) or not (Transfer).
You can also put calls on hold. Depending on your telephone system configuration, this means that the other person should hear music. When you are ready to talk to the caller again, use the Unhold button. Remember, the Hold button is not for transferring calls. It is purely to pause the call. If you want to transfer a call that is on hold, then first you will have to take the call off hold first.

You can use Send Digits to enter further digits during a phone call, when using an automated phone system for example. Clicking the Send Digits button changes the Actions panel to an alternate view of a numeric keypad like on a conventional phone. Click the numbers as you need them and click the Actions button to switch back.
