Abstract

An integrated messaging system uses existing messaging equipment to receive, store, retrieve and manage messages in media types and formats appropriate to each existing system using protocols which are specific to that system. Two or more systems are tightly coupled in that a message received in one system can be accessed from all systems. Coordination between messaging systems is achieved by a synchronizer system which periodically connects to each system by means of a standard interface and insures that messages created or received in one system are distributed or identified in all other messaging systems. Thus, the messaging systems can operate together even though they have different user interfaces, storage designs and formats and access and routing protocols. In one embodiment, a message received in one system is copied to the other system. In another embodiment, the header information in a message is preserved in a message created in the other system, but the message is not copied. The header information allows the message to be located and reproduced. In still another embodiment, one messaging system is designated as the single store for all messages.

Claims

1. Apparatus for use on a digital network for coordinating messages received in both a first messaging system which receives and stores messages in a first format and a second heterogeneous messaging system which receives and stores messages in a second format, the apparatus comprising:

a synchronizer connected to the network;

a first standard interface connecting the synchronizer to the first messaging system to allow the synchronizer to control the first messaging system;

a second standard interface connecting the synchronizer to the second messaging system to allow the synchronizer to control the second messaging system;

a first mechanism in the synchronizer for examining the second messaging system and for insuring that information is stored in the first messaging system corresponding to messages stored in second messaging system; and

a second mechanism in the synchronizer cooperating with the first mechanism for deleting messages stored in the second messaging system corresponding to the information stored in the first messaging system.

2. Apparatus according to claim 1 wherein the digital network has a user computer connected thereto and the apparatus further comprises means for presenting on the user computer messages stored in the first messaging system in the first format.

3. Apparatus according to claim 2 wherein the apparatus further comprises means for presenting on the user computer messages stored in the first messaging system in the second format.

4. Apparatus according to claim 1 wherein the first mechanism stores information identifying messages stored in the second messaging system.

5. Apparatus according to claim 1 wherein the first mechanism comprises a synchronization mechanism which is responsive to messages received at the second messaging system for generating messages in the first format containing equivalent information and storing the generated first format messages in the first messaging system.

6. Apparatus according to claim 1 wherein the first mechanism comprises a synchronization mechanism which is responsive to messages received at the second messaging system for generating messages in the second format containing equivalent information and storing the generated second format messages in the first messaging system.

7. An integrated multimedia messaging system for use on a digital network, the system comprising:

a first message server comprising a storage and connected to the network for receiving messages in a first format and for digitizing first format messages and storing the digitized first format messages in the storage along with state information indicating whether the first format messages have been read and identification information uniquely identifying each first format message;

a second message server comprising a storage connected to the network for receiving messages in a second format different from the first format and for digitizing second format messages and storing the digitized second format messages in the storage along with state information indicating whether the second format messages have been read and identification information uniquely identifying each second format message;

a synchronizer connected to the network for insuring that message information is stored in the first server storage for both first format messages stored in the first server storage and second format messages stored in the second server storage; and

a mechanism in the synchronizer which is responsive to second format message information being stored in the first server storage for accessing the second server using the message information stored in the first server to delete second format messages stored therein.

8. A system according to claim 7 further comprising a first workstation connected to the network including a message program for accessing the first server and retrieving messages stored therein and including a presentation mechanism for presenting both first format messages and second format messages to a user.

9. A system according to claim 7 further comprising a first workstation connected to the network including a message program for accessing the first server and retrieving messages stored therein, and further comprising a presenting mechanism for presenting first format messages and a conversion mechanism for converting second format messages to first format messages so that the first station can present second format messages.

10. A system according to claim 7 wherein the first server comprises a gateway mechanism which is responsive to second format messages received at the second server for generating first format messages containing equivalent information and storing the generated first format messages in the first server storage.

11. A method for use on a digital network for coordinating messages received in both a first messaging system which receives and stores messages in a first format and a second heterogeneous messaging system which receives and stores messages in a second format, the method comprising the steps of:

A. creating a synchronizer and connecting it to the network;

B. connecting the synchronizer to the first messaging system by means of a first standard interface to allow the synchronizer to control the first messaging system;

C. connecting the synchronizer to the second messaging system by means of a second standard interface to allow the synchronizer to control the second messaging system;

D. using a first mechanism in the synchronizer to examine the second messaging system and to insure that information is stored in the first messaging system corresponding to messages stored in second messaging system; and

E. using a second mechanism in the synchronizer to examine the first messaging system and to delete messages stored in the second messaging system corresponding to the information stored in first messaging system.

12. A method according to claim 11 wherein step D comprises the step of:

D1. storing information identifying messages stored in the second messaging system.

13. A method according to claim 11 wherein step D comprises the step of:

D2. in response to messages received at the second messaging system, generating messages in the first format containing equivalent information and storing the generated first format messages in the first messaging system.

14. A method according to claim 11 wherein the digital network has a user computer connected thereto and the method further comprises the steps of:

F. presenting on the user computer messages stored in the first messaging system in the first format; and

G. presenting on the user computer messages stored in the first messaging system in the second format.

15. A computer program product for use on a digital network for coordinating messages received in both a first messaging system which receives and stores messages in a first format and a second heterogeneous messaging system which receives and stores messages in a second format, the computer program product comprising a computer usable medium having computer readable program code thereon, the program code including:

program code for creating synchronizer connected to the network;
