Optional Calling Features
The Express 3000 SP fully supports optional calling features such as
three- or six-way call conferencing, call forwarding, caller ID, call re-
turn, call holding, call transfer, call rejection, call waiting, and mes-
sage waiting. To use these features, your touch-tone telephone must
