ABSTRACT:
Voice calls between multimedia workstations (1937-1939) of a LAN-based client-server multimedia communications system (1911) and telephones (1918-1919) of a telephone system (1912) are effected by an interface that comprises a pair of ISDN ports (1920 and 1940) interconnected by an ISDN link (1910) and that transfers ISDN control signals and user communications between the LAN (1936) and the telephone switching fabric (1916), and by proxy-user client software (21210 and 21212) that executes on the server (1933) of the multimedia system and converts control signals between the ISDN signals of the ISDN interface and a call processor (1914) of a telephone switching system (1913), and the middleware signaling of the server and its client workstations. The proxy-user client software comprises an object-oriented programming object, and each telephone that is engaged in a call with a workstation is represented in the multimedia system by its own instance (21210-1 to 21210-2) of the object.
