Learn how to use call park.
This feature, for analog phones only, allows you to place a call on hold so that it can later be retrieved from the same or another phone. Retrieving a parked call from another phone will not work if the analog phone with the incoming call has activated call diversion busy. (You must hear a busy signal to retrieve the call from another phone).
Note: The information on this page is applicable only to analog phone models at UCSD. You may need to check specific information about your phone and the features available to you.
