Abstract

A system and method for identifying users dropped from a conference call and rejoining the user to the call upon reconnection. Users can participate in the conference by connecting through different types of networks using a device having one or more types of communication lines. When a user is disconnected before the end of the conference (due to a bad mobile phone connection, for example), a bookmark is placed in the recording indicating the disconnection point. When the user rejoins the conference, the user is given the option to begin listening to the conference at the point where the user was disconnected. The user can issue playback-type requests, such as play, rewind, fast forward, etc., to review missed information. Other users are alerted by a characteristic tone when a user disconnects from the conference and by another characteristic tone when the disconnected user rejoins the conference.

Claims

1. A method of connecting telephone participants to a telephone call, said method comprising:

initiating a telephone call between a plurality of participants;

receiving a plurality of voice inputs from the participants, wherein the voice inputs include voice data;

storing the voice data in a memory area;

determining that a disconnection of a line connecting one of the participants to the telephone call has occurred, resulting in a disconnected participant;

identifying the disconnected participant;

retrieving a disconnection address from a storage location in the memory area that corresponds to a time of the disconnection;

storing an identifier corresponding to the disconnected participant and the disconnection address;

receiving a rejoin request from the disconnected participant requesting to rejoin the telephone call;

retrieving a portion of the voice data from the memory area that was stored after the time of the disconnection and before receiving the rejoin request; and

transmitting the retrieved portion of the voice data to the disconnected participant.

2. The method as described in claim 1 wherein the transmitting further comprises:

retrieving an accelerated transmission speed;

adjusting a transmission rate based upon the accelerated transmission speed; and

connecting the disconnected participant with the other participants in the telephone call upon completion of the transmission.

3. The method as described in claim 1 further comprising:

providing an audible signal to the participants that a rejoin request has been received from the disconnected participant.

4. The method as described in claim 1 further comprising:

receiving a skip transmission request from the disconnected participant;

stopping the transmitting in response to the receipt of the skip transmission request; and

connecting the disconnected participant with the other participants in the telephone call upon stopping the transmission.

5. The method as described in claim 1 further comprising:

receiving one or more playback requests from the disconnected participant during transmission of the retrieved portion, wherein the playback requests are selected from the group consisting of a rewind request, a fast forward request, a pause request, a query request, a stop request and a bookmark request; and

executing the playback requests against the retrieved portion.

6. An information handling system comprising:

one or more processors;

a memory area accessible by the processors for storing telephone call data;

a transmitter for transmitting voice input received over a data network;

a receiver for receiving voice data from the data network; and

means for determining that a disconnection of a line connecting one of the participants to the telephone call has occurred, resulting in a disconnected participant;

means for identifying the disconnected participant;

means for retrieving a disconnection address from a storage location in the memory area that corresponds to a time of the disconnection;

means for storing an identifier corresponding to the disconnected participant and the disconnection address;

means for receiving a rejoin request from the disconnected participant requesting to rejoin the telephone call;

means for retrieving a portion of the voice data from the memory area that was stored after the time of the disconnection and before receiving the rejoin request; and

means for transmitting the retrieved portion of the voice data to the disconnected participant over the data network.

7. The information, handling system as described in claim 6 wherein the means for transmitting further comprises:

means for retrieving an accelerated transmission speed;

means for adjusting a transmission rate based upon the accelerated transmission speed; and

means for connecting the disconnected participant with the other participants in the telephone call upon completion of the transmission.

8. The information handling system as described in claim 6 further comprising:

means for providing an audible signal to the participants that a rejoin request has been received from the disconnected participant.

9. The information handling system as described in claim 6 further comprising:

means for receiving a skip transmission request from the disconnected participant;

means for stopping the transmitting in response to the receipt of the skip transmission request; and

means for connecting the disconnected participant with the other participants in the telephone call upon stopping the transmission.

10. The information handling system as described in claim 6 further comprising:

means for receiving one or more playback requests from the disconnected participant during transmission of the retrieved portion, wherein the playback requests are selected from the group consisting of a rewind request, a fast forward request, a pause request, a query request, a stop request and a bookmark request; and

means for executing the playback requests against the retrieved portion.

11. A computer program product stored on a computer operable media for joining telephone participants to a telephone call, said computer programproduct comprising:
