Local call appearance key
The local call appearance key is the key you use to place and receive local calls.
For example, if your office is working overtime and everyone wants pizza, you
call the pizza delivery place on the local call appearance key. Similarly, you use
this key if you want to call one of your customers or suppliers or someone else at
your site.
Your telephone can have up to two local call appearance keys. Your system
administrator can tell you where these keys are and how they are labeled.
Online mode
When in online mode, calls initiated on the host call appearance key are directed
through the host PBX. Any long distance charges associated with calls placed
through the PBX over the PSTN are charged to the host PBX site. The display
on all digital telephones shows “Online Mode.”
Offline mode
When in offline mode, you cannot place calls through the host PBX over either
the IP network or PSTN. You can only place calls through your local telephone
service provider if your station has been granted locally controlled call
capability. The display on all digital telephones show “Offline Mode.”
Why offline mode is important
Your organization is concerned about telephone costs and, as such, wants to
ensure that the ISDN BRI line at your site is used for host-controlled calls during
business hours only. This is especially important when the ISDN BRI
connection between the host PBX and your site is defined as permanent (always
on) rather than on demand. A permanent ISDN BRI connection means the line
remains active all the time and incurs charges unless it is put into offline mode.
