Connections between external lines
With your BusinessPhone Communication Platform, 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
Communication Platform 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
• Try to avoid diverting calls to third parties before they
have answered
• If you are connected to two external lines, cancel one call
by pressing
R and the 1 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 reprogramming your
system.
Please ask your system administrator or contact our service centre
for more information.
