Abstract

A method is disclosed for messaging multimedia calls with a non-CCITT compliant switch when the intended recipient is unavailable. The method is used in connection with a telecommunication network which has an identified multimedia server. According to the method, multimedia calls from a caller, using a multimedia device running a first application and a second application, are messaged when the called party is unavailable. The method involves initiating a multimedia call to the called party using the first application and determining that the multimedia call is an unanswered call using the second application. Using the second application, the first application is signalled to indicate that the multimedia call was unanswered. In response to the signal, an X.25 packet message is sent from the multimedia device to the identified network based multimedia server. The multimedia device receives back a messaging address identifying a multimedia messaging server from the network based multimedia server. A second multimedia call is initiated from the multimedia device to the identified multimedia messaging server using the first application and the messaging address. The method then involves connecting to the multimedia messaging server indicated by the messaging address and recording a multimedia message on the network based multimedia messaging server.

Claims

1. In a telecommunication network including an identified multimedia server, a method of messaging multimedia calls from a caller, using a multimedia device running a first application and a second application, the method comprising the steps of:

initiating a first multimedia call to the called party using the first application;

determining that said first multimedia call is an unanswered call using the second application;

signalling the first application using the second application so as to indicate that said first multimedia call is said unanswered call;

responsive to said signal, sending an X.25 packet message from the multimedia device to the identified network based multimedia server;

receiving from the network based multimedia server, at the multimedia device, a messaging address identifying a multimedia messaging server;

initiating a second multimedia call from said multimedia device to said identified multimedia messaging server using the first application and said messaging address;

connecting to said multimedia messaging server identified by said messaging address; and

recording a multimedia message on said network based multimedia messaging server.

2. The method of claim 1 wherein following said connecting step the method includes the step of furnishing the caller with a multimedia greeting.

3. The method of claim 1 wherein, prior to said signalling step, the method includes the step of counting ringing cycles until a preselected number of ringing cycles has occurred.

4. The method of claim 1 wherein, prior to said signalling step, the method includes the step of waiting until a preselected period of time has elapsed.

5. The method of claim 1 wherein, following said signalling step, the method includes the step of displaying a message for the caller indicating that the call was an unanswered call.

6. The method of claim 5 wherein the method further includes the step of providing the caller with the option of invoking a messaging feature.

7. A method of multimedia messaging comprising:

initiating a messaging application and a watchdog application in a multimedia capable station having a display device;

initiating a first multimedia call to a party using said multimedia capable station;

establishing, as part of said initiation, a connection capable of passing X.25 packet messages between said multimedia capable station and a device in a telecommunication network;

signalling said messaging application, using said watchdog application, to indicate that said party is unavailable;

generating a first X.25 packet message in said multimedia capable station and sending said X.25 packet message to said device in said telecommunication network;

receiving a second X.25 packet message from said device server including information identifying a multimedia messaging server capable of recording multimedia messages and furnishing previously stored multimedia messages to multimedia capable stations;

initiating a second multimedia call from said multimedia capable station to said identified multimedia messaging server; and

recording a multimedia message for said party on said identified multimedia messaging server.

8. The method of claim 7, further including the step of displaying a message on said display device indicating that said first multimedia call was unanswered.

9. The method of claim 7, further including the step of identifying from said received X.25 packet message data indicating a connection address for said multimedia messaging server.

10. The method of claim 7, further including the step of displaying, on said display device, a previously stored multimedia message furnished by said multimedia messaging server.
