Abstract

A telephony system is formed by a base station and subscriber devices. The telephony system has a callback system for producing callback signals by acting on a sound device, for example, by ringing a sound via the earphone for the users. The callback signals are associated with a message which may be a sound or visualized message.

Claims

1. A telephony system formed by a base station and at least one subscriber device intended for at least one user, the telephony system comprising a callback system for producing callback signals for said at least one user, wherein a message may be assigned to each callback signal, said message being a displayed text including a reason for said callback signal, and wherein said callback system includes a memory for storing data related to said callback signal;

said data including a first field indicative of whether said callback signal should be sent to said at least one subscriber device, a second field which includes a time said callback signal is to be sent to said at least one subscriber device, a third field which includes said text, and a fourth field which includes an identification of said at least one subscriber device.

2. A telephony system as claimed in claim 1, characterized in that it satisfies the DECT standard.

3. A telephony system as claimed claim 1, characterized in that the messages are visualized messages.

4. A system as claimed claim 1, characterized in that said messages are empty messages.

5. A method implemented in a system as claimed in claim 1, recording a callback request comprises the following steps:

establishing a link between the at least one subscriber device and the base station,

choosing of a callback time for forming a first callback data,

choosing between a spoken message or written message for forming a second callback data,

recording of the message, and

writing said callback data in a table addressed by the identification of the subscriber devices.

6. A method as claimed in claim 5, wherein effecting a callback the following steps:

reading said table by carrying out this reading in succession for each of said subscriber devices,

analyzing of said callback data,

establishing a link to a respective subscriber device determined by said analysis,

transmitting of a callback signal, and

delivering of the message.

7. A subscriber device suitable for such a telephony system as claimed in claim 1, comprising means for writing said callback data in a table.

8. A base station suitable for such a telephony system as claimed in claim 1, comprising means for containing said table and managing this table and means for triggering the desired callbacks to the subscriber devices.

9. The telephony system of claim 1, wherein said reason had been typed using said at least one subscriber device during formation of said callback signal.

10. The telephony system of claim 1, wherein said reason had been typed using said at least one subscriber device for being displayed back on said at least one subscriber device.

11. The telephony system of claim 1, wherein said callback signal includes a sound recording recorded by said at least one user for playback.

12. The telephony system of claim 1, wherein said callback signal includes a sound recording of said reason.

13. The telephony system of claim 1, wherein said callback signal includes a sound recording of said reason recorded during formation of said callback signal.

14. A telephony system comprising:

a handset; and

a base station which communicates with said handset;

wherein said telephony system is configured to allow a user of said handset to request a callback signal from said base station, said callback signal including a displayed text having a reason for said callback signal, and

wherein said base station includes a memory for storing data related to said callback signal;

said data including a first field indicative of whether said callback signal should be sent to said handset, a second field which includes a time said callback signal is to be sent to said handset, a third field which includes said text, and a fourth field which includes an identification of said handset.

15. The telephony system of claim 14, wherein said reason had been typed using said handset during formation of said callback signal.

16. The telephony system of claim 14, wherein said reason had been typed using said handset for being displayed back on said handset.

17. The telephony system of claim 14, wherein said callback signal includes a sound recording recorded by said user for being replayed.

18. The telephony system of claim 17, wherein said sound recording is recorded in said base station.

19. The telephony system of claim 14, wherein said callback signal includes a sound recording of said reason.

20. The telephony system of claim 14, wherein said callback signal includes a sound recording of said reason recorded during formation of said callback signal.
