Vertical Communications TeleVantage 7.5 manual Using line appearances, Using PDNs, Using SDNs

With a digital feature phone you can do the following:

QUse line appearances to handle multiple calls simultaneously, and share lines between phones. See the next section.

QUse 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:

QPrimary Directory Numbers (PDNs). These are lines assigned to you.

QSecondary 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.
