forward to voice mail or not. Single line telephones must have the system adminis-
trator program this feature for them.
CALL PICKUP
With directed call pickup, a user can answer calls ringing at any station by dialing a
code plus that extension number. The group pickup feature allows the user to an-
swer any call ringing within a pickup group. Pickup keys may be customized with
extenders to allow pickup from a specific station or pickup group. The DCS 50si
has 20 programmable pickup groups.
DIAL BY NAME
Each system and personal speed dial number can have an associated directory
name. A speed dial number can be selected by scrolling alphabetically through the
directory name list. This on-line “directory” allows the user to look up and dial num-

Programmable keys can be assigned as DSS keys and associated with extension
