external phone numbers allowed on speed dial buttons for the Polycom VVX 450

You can take previously called numbers and add them to favorites, then access them by pressing the up arrow on the phone: To add - on my VVX-450, for example, Home, 4,3,select recent call, OK (center button), "Save" (soft button below display), Edit [using keypad and arrows], and soft button "Save" again.

On my non-RC Poly VVX-450, once I add a few entries to the Presence buttons. Some added favorites creep up onto the presence keys as well, including outside numbers. Curious. Those entries can get pushed back down into Favorites as Presence entries are added.

Most phones on my client's system are RC-Poly phones, so I will be checking to see if the behavior is the same with these phones.
