Abstract

For providing a telephone service between a source telephone and a target telephone, the target telephone is equipped with an incoming channel and an outgoing channel. Upon an incoming call from the source telephone received at the target telephone via the incoming channel being unanswered, the target telephone simultaneously establishes an outgoing call with a server via the outgoing channel. This creates a bridge between the source telephone and the server, thereby rendering a message prompt produced by the telephone service audible at both the source and target telephones. The server may be a voice mail system that allows call screening by the target telephone of a call by the source telephone if the target telephone does not go off-hook within a predetermined time interval. Or the server may provide a personalized ring signal or message to the target telephone until the target telephone goes off-hook.

Claims

1. A method for directing a telephone service to a source telephone upon making a call to a target telephone, said method comprising:

(a) allocating the target telephone an incoming channel and an outgoing channel;

(b) upon receiving an incoming call from the source telephone via the incoming channel, detecting whether the target telephone goes off-hook;

(c) based on whether the target telephone goes off-hook, simultaneously establishing an outgoing call between the target telephone and a server providing said telephone service via the outgoing channel; and

(d) connecting the incoming channel to the outgoing channel at the target telephone so as to establish a connection via the target telephone between the source telephone and said server.

2. The method according to claim 1, wherein the server is directed to the target telephone via the outgoing channel if the target telephone does not go off-hook within a predetermined time interval.

3. The method according to claim 2, wherein the server is part of a Voice Mail System.

4. The method according to claim 1, wherein the server is directed to the target telephone via the outgoing channel until the target telephone goes off-hook.

5. The method according to claim 4, wherein the server conveys a personalized ring signal or message to the target telephone.

6. The method according to claim 1, wherein the connection via the target telephone between the source telephone and the server is effected via a PSTN switch.

7. The method according to claim 1, wherein the connection via the target telephone between the source telephone and the server is effected via a soft proxy.

8. The method according to claim 1, further including:

directing media and signaling between the source telephone and the target telephone via a gateway for effecting protocol conversion between PSTN and IP telephony protocols.

9. A telephone including:

an incoming channel for connecting to a source telephone,

an outgoing channel for connecting to a server adapted to provide a telephone service, and

a switch adapted to connect the incoming channel to the outgoing channel so as to direct the telephone service to the source telephone.

10. The telephone according to claim 9, wherein:

the switch is responsive to an incoming call received from a source telephone via the incoming channel for simultaneously establishing an outgoing call between the target telephone and the server via the outgoing channel conditional on an off-hook status of the target telephone;

thereby establishing a connection between the source telephone and the voice mail system so as render a message prompt produced by the server at the target telephone and conveying said message prompt to the source telephone.

11. A telephone system including:

a target telephone having an incoming channel and an outgoing channel;

a source telephone coupled to the target telephone via the incoming channel;

,

a server coupled to the target telephone via the outgoing channel for providing a telephone service; and

a switch in the target telephone adapted to connect the incoming channel to the outgoing channel so as to redirect a call received from the source telephone on the incoming channel to the server while maintaining connection to the source telephone.

12. The telephone system according to claim 11, wherein the server conveys the service to the target telephone via the outgoing channel if the target telephone does not go off-hook within a predetermined time interval.

13. The telephone system according to claim 11, wherein the server is part of a Voice Mail System.

14. The telephone system according to claim 11, wherein the server is directed to the target telephone via the outgoing channel until the target telephone goes off-hook.

15. The telephone system according to claim 14, wherein the server conveys a personalized ring signal or message to the target telephone.

16. The telephone system according to claim 11, including a PSTN switch for effecting the connection via the target telephone between the source telephone and the server.

17. The telephone system according to claim 11, including a soft proxy for effecting the connection via the target telephone between the source telephone and the server.

18. The telephone system according to claim 11, further including:

a gateway coupled between the source telephone and the target telephone for effecting protocol conversion between PSTN and IP telephony protocols.

19. A method for directing a telephone service to a source telephone when making a call to a target telephone, said method comprising:

(a) establishing an outgoing call between the target telephone and a server providing said telephone service via an outgoing channel; and

(b) connecting an incoming channel to the outgoing channel at the target telephone so as to establish a connection via the target telephone between the source telephone and said server.

20. The method according to claim 19, wherein the server is connected to the target telephone via the outgoing channel if the target telephone does not go off-hook within a predetermined time interval.

21. The method according to claim 20, wherein the server is part of a Voice Mail System.

22. The method according to claim 19, wherein the server is connected to the target telephone via the outgoing channel until the target telephone goes off-hook.

23. The method according to claim 22, wherein the server conveys a personalized ring signal or message to the target telephone.

24. The method according to claim 19, wherein the connection via the target telephone between the source telephone and the server is effected via a PSTN switch.

25. The method according to claim 19, wherein the connection via the target telephone between the source telephone and the server is effected via a soft proxy.

26. The method according to claim 19, further comprising:

connecting media and signaling between the source telephone and the target telephone via a gateway for effecting protocol conversion between PSTN and IP telephony protocols.
