Patent ID: 7002953

Claim:
A system for transferring multimedia data between processes generated by software programs each running on information processing terminals, wherein the information processing terminals are capable to communicate with each other through at least one call connection controller that accommodates a plurality of extension terminals, wherein each call connection controller comprises: a database for storing association information when an association operation has been performed between an extension terminal and an information processing terminal, which are both connected to the call connection controller; a determining section for determining the presence or absence of an information processing terminal that has completed the association operation and a status of a software program on the information processing terminal; and a communications controller controlling such that, during communication between a first extension terminal and a second extension terminal, when first and second information processing terminals that have completed the association operations with the first and second extension terminals have been found and both of software programs on the first and second information processing terminals are ready and currently unused, multimedia data starts transferring between processes generated by the software programs running on the first and second information processing terminals, respectively.
