It is possible using the Super Copy option. To copy an existing phone and copy the directory numbers, speed dials, busy lamp field/speed dials, and service URLs that are associated with the phone, locate the appropriate phone as described in "Finding a Phone" section, click the Super Copy button next to the phone that you want to copy, and continue with Step 5.
