8.3.5 Conference
Subscriber A can set up a conference call with several subscribers. There are two
types of conference:
• Variable conference: The conference is set up one subscriber at a time. The sub-
scribers are called one after the other.
• Preconfigured conference: Here the conference participants are preconfigured
in the system configuration and are all called up at the same time.
