Abstract

A method of recording and delivering a voice message from a calling telephone (1) to a called telephone (2) in the event that the called telephone (2) cannot be reached. A voice message (12) is recorded at the calling telephone (1) and is stored there until the calling telephone (1) receives a message (10) from the telephone network (3) that the called telephone (2) can now be reached. Upon receipt of this message (10), the calling telephone (1) initiates a call to the called telephone (2) and replays the recorded message (14) over the open voice channel.

Claims

1. A voice communication method comprising:

initiating a telephone call from a first telephone to a second telephone;

in the event that a voice channel cannot be opened between the first telephone and the second telephone, recording a voice message at the first telephone; and

subsequently transmitting said recorded message directly from the first telephone to the second telephone without necessarily requiring further user input, and wherein

both the first and second telephones are cellular telephones and subscribe to the same or different cellular telephone networks, the method further comprising the steps of;

converting the recorded message at the first telephone into a data signal;

transmitting the data signal to the second telephone over a signaling channel or channels;

receiving the data signal at the second telephone over the signaling channel or channels; and

converting the data signal back to a voice signal for subsequent playback.

2. A method according to claim 1, wherein the first telephone and the second telephone subscribe to a GSM cellular telephone network, said data signal being transferred as a short message service (SMS) message or a set of concatenated SMS messages.

3. A method according to claim 1 and comprising transmitting a pre-recorded voice message (e.g. a voice header) together with said recorded message from the first telephone to the second telephone.

4. The method of claim 1 wherein the transmitting of the recorded message from the first telephone to the second telephone is done without user input.

5. A telephone system comprising:

telephone call initiating means for initiating a call from a first telephone to a called telephone;

detection means for detecting when a voice channel cannot be opened to the called telephone;

recording means in the first telephone for recording a voice message in the first telephone as a response for the event that said voice channel cannot be opened, the first telephone further adapted to convert the recorded message into a data signal; and

transmitting means in the first telephone for automatically transmitting the recorded message directly to the called telephone over at least one signaling channel and means for receiving the data signal at the second telephone over the signaling channel and converting the data signal back to a voice signal for subsequent playback;

wherein both the first telephone and the called telephone are cellular telephones and subscribe to the same or different cellular telephone networks.

6. A telephone according to claim 5, wherein the telephone subscribes to a GSM network, said signal processing means being arranged to transmit the recorded message as an SMS message or as a set of concatenated SMS messages.

7. A voice communication method comprising:

initiating a telephone call from a caller using a first telephone to a called party associated with a second telephone over a telephone network;

detecting in the telephone network that a voice channel cannot be opened between the first telephone and second telephone;

sending a signaling message from the telephone network to the first telephone that the voice channel cannot be opened;

recording a voice message from the caller to the called party at the first telephone device;

transmitting a message from the telephone network to the first telephone to indicate when the voice channel can be opened to the second telephone;

opening the voice channel from the first telephone following receipt of said message; and

subsequently transmitting said recorded message to the second telephone over the open voice channel; and

wherein both the first and second telephone are cellular telephones and subscribe to cellular telephone networks.

8. The method of claim 7 further comprising the steps of:

converting the recorded message at the first telephone into a data signal;

transmitting the data signal to the second telephone over a signaling channel or channels;

receiving the data signal at the second telephone over the signaling channel or channels; and

converting the data signal to a voice signal for subsequent playback to the called party.

9. A voice communication method comprising:

initiating a telephone call from a first telephone to a second telephone;

in the event that a voice channel cannot be opened between the first telephone and second telephone, recording a voice message at the first telephone wherein both the first and second telephones are cellular telephones and subscribe to cellular telephone networks;

converting the recorded message into a data message or set of data messages;

transmitting the data message or set of data messages to the second telephone over a signalling channel or channels;

receiving the data message or set of data messages at the second telephone over the signalling channel or channels; and

converting the data message or set of data messages to a voice signal for subsequent playback.
