Delayed Ringing
(NBX Business Telephone and Attendant Console only) The Delayed
Ringing feature prevents a telephone on a shared line from ringing on a
specific telephone until the incoming call rings on another telephone a
specified number of times.
A shared line can be a bridged extension or an incoming analog
telephone line that is mapped to more than one telephone.
Example:
A telephone extension is programmed to appear on a manager’s
telephone and on the assistant’s telephone. When a call comes in to the
manager on that extension, the assistant’s telephone rings a specified
number of times (typically, 4 rings) before the call audibly rings on the
manager’s telephone. Even during the first silent rings, the line’s status
light on the manager’s telephone flashes, allowing the manager to
answer the calls if required.
Pulse Dialing
In some locations, analog telephone users must dial telephone calls using
pulse dialing instead of tone dialing (also called Dual Tone Multi
Frequency, or DTMF , dialing).
Your administrator must configure the Analog Line Card ports for pulse
dialing.
Examples:
■
Some of your telephone lines are provided by a telephone company
that supports only pulse dialing while other lines are provided by a
different telephone company that support DTMF dialing.
■
Your organization’s telephone service provider offers low-cost,
pulse-dialing-only service.
■
In some situations, you must switch to DTMF dialing during a call. For
example, if your call is answered by an automated attendant that
requires that you enter information from your telephone keypad, you
must typically enter the information using DTMF dialing.
