ABSTRACT:
A telecommunications system (TS2) comprises a data network (IN1) and a telephone network (PSTN1) to which subscribers (AB1, AB2) are connected. Each subscriber has a telephone (T1, T2) with A-number transfer and a computer terminal (D1, D2) connected through access devices (ACD1, ACD2). A server (SR1) holding the subscribers' home pages and a directory (DS1) holding different identities (TELO1, TELO2, TELH2, EMAILO1, URL2) of the subscribers is connected to the data network. The directory (DS1) is public, which enables the subscribers to enter their respective identities and obtain the identities of other subscribers. One subscriber (AB1) calls the other (AB2) on his home telephone number (TELH2), which is transferred to the computer terminal (D1) of the caller (AB1). The subscribers (AB1, AB2) can talk, the caller (AB1) can obtain the identities of the called party (POSTS2) through his computer terminal (D1) from the directory (DS1) and use this information, for example, to open the called party's home page on the server (SR1). By A-number transfer the called party (AB2) can obtain the identities (POSTS1) of the caller (AB1), in a corresponding way, to his computer terminal (D2) from the directory (DS1). This way of communicating and keeping a directory is possible because the directory (DS1) is public. Advantages are, i.a. that the communication is simplified and the identities of other subscribers can be obtained easily.
