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.

If a name is available to the external caller‘s number in your system, it is shown alternating to the number. (Please contact your system administrator whether the feature name presentation is available in your system)
