supported by the system. The services from the public net differ
from market to market. Please ask your system administrator
which features are available.

When you establish an outgoing external call, the public number of
your system and your extension number will be sent to the called
party. If the number of the answering party is different from the
dialled one (for example, after a diversion), you will also be informed
about the answering party's number.
When you answer an incoming external call on your phone (or from
another phone), you will see the caller's number on the display.
Your public number will be sent to the caller.
