摘要

In a method for conditional build-up of a telescopic difference session communication contact with a plurality of telecommunications conference session_id - subscriber devices, wherein a at least one telecommunications conference session_id - subscriber device by means of a subscriber devices - group having telecommunications conference session_id - subscriber groups - identification is identified, a predefined telescopic communication kon difference session - construction condition is checked with the inclusion of two telecommunications conference session_id - server. A first telecommunications conference session_id - server receives a request to build up of a telescopic communication contact resulting difference session, and a second telecommunications conference session_id - server condition relevant information is determined for the purpose of checking the predefined telecommunications conference session_id - construction condition.
