Abstract
A low-cost implementation of a voice message system is indicated. To that end, a digital signal processor (DSP) and a second memory (ROM) with program modules for executing the functions of "automatic operator" and/or "mailbox" are integrated in a digital telephone (TE4). In addition, the digital telephone (TE4) is able to execute an "individual messages" function, whereby a message intended only for another telephone (TEA) is transmitted to this other telephone (TEA) by means of the digital telephone (TE4).
Claims7
A digital telephone (TE4) comprising an interface means (S.sub.04) providing a connection with a link (S.sub.0) to a digital communications network (ISDN), said link having at least one further digital telephone (TE1, . . . , TE8) connected thereto;
- a first control means (HOST) connected to such interface means for controlling functions executable with the digital telephone (TE4);
- a first memory (MEM) for storing speech connected to a digital signal processor (DSP) connected to both said first control means and said interface means;
- a second memory (ROM);
- and program modules stored in the second memory (ROM) connected to said digital signal processor, said program modules for executing a first, automatic operator function, in which speech data is read from the first memory (MEM) and transmitted over the digital communications network (ISDN) to another telephone (TEA) having a separate link to the digital communications network (ISDN), and the digital telephone (TE4), in response to signaling information from the other telephone (TEA), initiates establishment of a call from the other telephone (TEA) to the at least one further digital telephone (TE1, . . . , TE8), and/or said program modules executing a second, mailbox function, for both the digital telephone (TE4) and the at least one further digital telephone (TE1, . . . , TE8).
