ISDN Facilities
Note: This section only applies to the Standard telephone.
This chapter is only relevant when your system is connected to a
digital trunk line (ISDN-trunk line). It provides a general view of all
the (supplementary) services available from the public net which
are supported by the system. The services from the public net
differ from market to market. Please ask your system
administrator which features are available.
Number identification
The main difference compared to the analog public net is the
number identification between the connected parties.
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.
