three party service (ISDN) (3PTY)

Three-party conferencing, the Three Party Service (3PTY), is a feature of telephone services in digital fixed and mobile networks. Three-party conferencing allows three parties to call each other at the same time, each to each.

The connection for a three-party conference can be established by the third party trying to reach the call partner who is currently in an active call. After the call waiting and the signaling of the connection request, the call waiting party is added to the existing connection. On the other hand, a subscriber of an existing connection can dial a third subscriber himself and include him in the conversation (connection). With this type of connection, two connections are always active.

With the three-party conference feature, negotiations, voting and small conferences can be carried out quickly and directly. Each conferee can talk on the phone with everyone else at the same time.
