For non-DISA calls to a Private Incoming Line, the IPS will ring the
fi
rst available extension in
the appropriate (day or night) list. If the extension does not answer within the “Rollover After
Call to Extension” time, the call will start ringing at the next available extension in the Private
Incoming List, not including the extension which is currently ringing. This proccess will repeat
until the incoming caller hangs up and the ringer signal is no longer present. Thus, the
fi
rst two
available extensions in the Private Incoming List will alternately ring until the call is answered or
the ringer input goes away.
One typical con
fi
guration would be to put the Operator as the second extension in a Private
Incoming List. If the Operator does not answer, the call will start ringing at an available Rollover
Extension. Another typical con
fi
guration would be to put an answering machine or voice mail
unit extensions in the list. Since the IPS unit allows both Day mode and Night mode lists, you will
want to make sure that an answering machine or voice mail is the
fi
rst or second extension in the
night list so that calls received after hours will never go unanswered.
In any case, it is best that the Private Incoming List be
fi
lled with enough entries so that the call
always has a place to ring. If there is no available extension in the Private Incoming List, the call
will park at the
fi
rst extension in the list and give a beep signal to that extension if it is a single
line telephone every few seconds to inform them that a call is waiting.
