Customized Features
Line Ringing Options are available to allow people a choice in how they are notified
of an incoming call. The system is installed with Normal Ringing. Also available is
Abbreviated Ringing (rings for twelve seconds only), Delayed Ringing (line doesn't
start ringing until twelve seconds after call comes in), and No Ringing. Delayed
Ringing is handy when arranging a back-up person to answer calls that a receptionist
may be unable to get. If s/he doesn't answer a call within twelve seconds, it will
automatically begin ringing at the back-up station. The No Ringing option is good for
lobbies or conference rooms.
There are more. All customizing involves the "Controller" which is a boxlike device
mounted near the incoming telephone lines, and the intercom #10 telephone set. If
you do not yet have a System Administrator in charge of maintaining and
programming the SPIRIT Communications System, someone should be designated.
That person will then be responsible for implementing the already mentioned
customized features and the others outlined in the Administration Manual.
