4-12 USING TELEVANTAGE
With a digital feature phone you can do the following:
Q Use line appearances to handle multiple calls simultaneously, and share lines between
phones. See the next section.
Q Use the phone’s flexible buttons if TeleVantage features have been mapped to them. See
“Using custom-mapped TeleVantage commands” on page 4-13.
Using line appearances
Line appearances allow the digital feature phone to handle multiple simultaneous calls, with
each “line” mapped to a programmable button. For example, if you are on a call on a Line 1
button, an incoming call might ring Line 2, and you can press Line 2 to put the first call on hold
and answer the new call. You can have calls on hold on multiple lines and switch between them
simply by pressing the buttons.
You can have as many line appearances as there are programmable buttons on your phone.
There are two types of line appearances:
Q Primary Directory Numbers (PDNs). These are lines assigned to you.
Q Secondary Directory Numbers (SDNs). These are lines that are mapped to another
user’s PDNs, so that the line is shared between the two of you. When a call is ringing on
an SDN, either you or the other user can pick up. It is common to have several SDNs,
mapping to all of the PDNs on the other user's phone, so you can pick up any call the
other user may receive.
Using PDNs
A digital feature phone button configured as a PDN gives you an extra line with which to place
or receive calls. When an incoming call arrives while you are on the phone, the call rings the
next available PDN. To answer the incoming call, either press that PDN button, or press and
release the hook briefly. The previous call is put on hold.
Using TeleVantage call waiting in conjunction with PDNs gives you an unlimited number of
lines. Once all PDN lines are in use, a new incoming call causes the call waiting beep to sound,
and you can press
Flash to take the call. You can continue to add new calls in this manner, and
can switch between them using the telephone commands or the ViewPoint Call Monitor.
Note: When the user places outbound calls, the highest-numbered available PDN is used.
When incoming calls arrive, the lowest-numbered available PDN is used. This provides a visual
cue when multiple calls are being handled.
Using SDNs
An SDN is a digital feature phone button configured as a extra line that refers to a PDN of
another user. When a call comes in to the primary user’s phone, both the primary user’s PDN
and your SDN ring, and either you or the other user can pick up. SDNs can be set and changed
by your system administrator only.
