Abstract
A switching system (100) inserts H.320 multi-media protocol-terminating resources (156) into an existing call dynamically, only when the resources are needed, and also removes the resources from an ongoing call dynamically, when the resources are no longer needed, whereby the switching system can provide call features such as hold, conference, disconnect, drop, and transfer, to an H.320 multi-media call and can do so spontaneously, whenever desired during the call, without tying up the resources for the duration of the call even when they are not needed. To extend these capabilities to both single-channel and multi-channel multi-media ISDN BRI calls, the switching system associates a plurality of calls that constitute the individual channels of a multi-channel call and treats the associated calls identically and in unison for purposes of insertion and removal of resources and the providing of features.
