Message Services
Message Services
Your extension also offers text message services that enable you to
exchange mini-messages over the ISDN network with internal or
even external parties.
The available services include:
•
When placing a call, you have the option of transferring a mini-
message to your called party, in case he/she does not answer
your call, or has an ongoing call.
• In the same way, when you receive a call, you may consult a
mini-message sent to you by the party who attempted to
contact you.
You also have the option of a call forward to mini-messaging service.
This is also called the call forward on absence service. This does
not consist of a call forward in its truest sense; your incoming calls
are not re-directed. Rather, the absence message that you selected
when defining your call forward will be automatically transmitted to
the party who is trying to contact you.
For this purpose, your facility may make 10 pre-formatted mini-
messages available to you for one of the aforementioned purposes.
Note:
In relation to using these services with external parties, this
assumes that they are also ISDN network users, and that
they have ISDN terminals that are compatible with the mini-
messaging service. Certain extensions (such as yours) may
be permanently protected against the automatic use of this
call forward on absence service for external parties. In this
case, the text messaging services are only applicable internally
within your facility.
