Setting up a conference

A user can set up or prepare a conference call with up to 6 users. This can be done in four different ways:

"Conference bridge": The conference participants choose a specific call number and are connected with the conference after entering a PIN.
"Preconfigured conference": Here the conference participants are preconfigured in the system configuration and are all called up at the same time.
"Variable conference": Here the conference participants are all listed in the same dialling string 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.

notes:

Conference participants hear an attention tone when they join the conference. This tone can be switch off on the entire system. Comply with the national data protection terms. With a three-party conference in the public exchange, the signalling depends on the network provider.
Conferences take up hardware resources. Up to 6 conference participants are allowed in a conference.
If one or more users are external users or virtual network PISN users, the settings authorising exchange-to-exchange traffic will have to be observed.
On SIP phones of the Mitel 6700 SIP / 6800 SIP series, the Mitel BluStar 8000i and a number of standard SIP phones, three-party conferences are possible locally on the phone. For this, the Multi lines in the terminal configuration must be at least 2 and the parameter Conference circuit = In phone.
