Abstract

A communication system includes subscriber terminals which can be coupled via at least one switch, and to which subscriber terminals, several call numbers can be assigned for which telecommunication parameters are definable. The subscriber terminals each store respective telecommunication parameters. In the case of a change of assignment of a subscriber call number from a first subscriber terminal to a second subscriber terminal, the telecommunication parameters belonging to the subscriber call number are transmitted to the second subscriber terminal. The communication system is preferably implemented in ISDN switching systems with ISDN telephones as terminals.
