ABSTRACT:
The invention relates to a method for the provision and allocation of call numbers in a telecommunication network. According to said method, the call numbers are allocated to the subscribers of the telecommunication network, in addition to the available subscriber call numbers. A plurality of number contingents containing temporary anonymous TAC call numbers is made available and allocated to at least one management entity. The TAC call numbers of the number contingent can be individually or collectively allocated to the subscribers upon request, e.g. from a subscriber, by precisely allocating a TAC call number of a contingent to an available subscriber call number.
