Connections between external lines
With your BusinessPhone PBX, you can establish an external call
diversion or a conference with more than one external party or
transfer an external call to another external destination (e.g. a
mobile phone). These features are very useful for everyday
business life.
Note: When these features are used, your BusinessPhone
will occupy at least two external lines.
However, there may be disadvantages in connecting to several
external lines. We would therefore like to draw your attention to the
following:
•
Please do not transfer external calls to an external
Mailbox, to information systems or to external parties
before they have answered.
• Cancel your calls by pressing the Clear key.
If the external parties are not persons (Mailbox, automated
information or attendant systems, etc.), connections on external
lines can last a long time, which can be costly. Moreover, such calls
may occupy two of your system’s external lines. You can restrict
connections between the external lines by re-programming your
system.
Please ask your system administrator or contact our service center
for more information.
