## Conference

## Definition

Conference means that three or more internal or external parties can participate in a call.

## Use

Conference is used when several parties wish to converse without leaving their rooms-/workstations.

As several external parties can participate also this means that telephone meetings can be held via the national or international network.

Calls to internal directory numbers via the public network or private network have the possibility to be translated into DDI numbers by the individual number translation table.

For further information please refer to the document “Individual Number Translation on page 1 (170/155 34-ASB 150 02 Uen).

## Operation

The person who initiates a conference call is designated conference leader.

### Initiation of conference

- Conference leader makes call to first participant in conference and waits for answer
- Participant is informed that he/she will be participating in conference and conference leader asks participant to wait
- Conference leader initiates inquiry call to participant 2 and waits for answer.

- On answer the latter is informed that he/she will be participating in a conference

The menu text conf signifies only that the system permits a conference. However the function can be prevented on account of the extensions' categories.

### Connection of more participants

The conference leader can connect more parties by initiating a new inquiry.

### Disconnection of a conference

#### Three party conference

When one of the participants leaves the conference this becomes a normal two-party call.

#### Multiparty conference

If the conference leader leaves the conference all participants will be disconnected.

If any other participant leaves the conference he/she will go free but the other participants continue the conference.

## Capacity

Up to six participants, internal and external, can participate in a conference.

The number of external participants is selectable via programming.

Up to 60 parties in the system can be interconnected in various conferences.

## Limitations

Only the conference leader can initiate inquiry in order to access more participants.

Other participants can only leave the conference by disconnecting.

Normally no check is made in the traffic group matrix in conjunction with the establishment of a conference.

If this kind of restriction is required contact your supplier.

Intrusion on a conference participant is not permissible.

Conferences cannot be initiated from hotel guestroom telephones.
