A sequential calling system that prioritizes the last successfully reachable telephone number

摘要

A waiting time optimization for a caller of a called party having a number of telephone numbers is obtained by a device and a method for establishing a telecommunication connection from a caller to a called party via at least one telecommunication network, in which the called party can possibly be reached on a number of telephone numbers stored in the telecommunication network. A telecommunication connection between the caller and the called party is set up in each case successively attempted on the stored telephone numbers by dialing in each case one of the stored telephone numbers of the called party until a telecommunication connection to the called party has been successfully set up. When a telecommunication connection has been successfully set up, the telephone number of the called party on which this successful setting-up took place is stored in the telecommunication network. In the case of a successive calling of stored telephone numbers of a called party, the stored telephone number of this called party on which a telecommunication connection has last been set up successfully is called as the first or second telephone number.
