9. 5. 5 Conference
User A can set up or prepare a conference call with several users. This can be done in
four different ways:
• Variable conference: Here the conference participants are all listed in the same dial-
ling string and are all called up at the same time.
• Preconfigured conference: Here the conference participants are preconfigured in
the system configuration and are all called up at the same time.
• Three-party conference (conference from enquiry call): The conference is set up
one participant at a time. The participants in the conference are called one after the
other and connected individually (see "Three-party conference from an enquiry call",
page 362).
• Conference bridge: The conference participants choose a specific call number and
are connected with the conference after entering a PIN (see "Conference bridge",
page 363).
