Abstract
In a communication system (KS), communication terminals (KA) provided for a legitimacy check are allocated to at least one inhibit dial evaluation routine (SWABE). In the framework of a call (ar), the call numbers (zrn) communicated to the inhibit dial evaluation routine (SWABE) as well as the call number (rnr) of the respective communication terminal (KA) are acquired and call numbers (zrn) or, respectively, call number combinations (rnr,zrn) that cannot be evaluated are reported to an application means (PC) via an application interface (acl). The calls (ar) are held in the communication system (KS) until the communicated call numbers (zrn) or, respectively, call number combinations (rnr, zrn) have been checked in the application device (PC) in view of their legitimacy and a legitimacy result (acl-amo) has been communicated from the application device (PC) to the communication system (KS). An advantage of the inventive method may be seen therein at only one inhibit dial evaluation routine (SWABE) need be established in the communication system (KS) for the communication terminals (KA) to be checked. Thus, the legitimacy checking of call numbers (rnr, zrn) of incoming calls (ar) is realized with the lowest possible additional outlay in the communication system (KS).
