Apparatus for connecting telephone switch to fixed telephone network or PSTN via a radiotelephone network of GSM type or type derived therefrom. A fixed radiotelephone terminal (RT) has a processor that identifies calls containing an identity belonging to a predetermined set of international mobile subscriber identities (IMSIs), and calls containing an identity belonging to a predetermined set of temporary mobile subscriber identities (TMSIs), both of the sets corresponding to user terminals (UT1, . . . , UT10) which are connected to the switch. The radiotelephone network issues a distinct invoice for each user terminal (UT1, . . . , UT10) even though the same fixed radiotelephone terminal (RT) is used by a plurality of different users, and the radiotelephone network can perform direct inward dialing to each user terminal (UT1, . . . , UT10). |
