ABSTRACT:
In a telecommunications system (8) that comprises communications endpoints (14-15), communications resources (18-20), a communications server (10) that includes a media manager (21), and a network (12) that interconnects them all, a first endpoint (14) provides the media manager with an offer of a connection to a second endpoint (15) that specifies attributes desired for the connection by the first endpoint. The media manager registers the request and forwards it to the second endpoint. When the second endpoint responds with an acceptance of the connection that specifies attributes desired for the connection by the second endpoint, the media manager compares the registered offer with the received acceptance to determine any resources that are needed to bridge any differences between their attributes and to effect the connection. The media manager then marshals any needed resources for the connection, sends a modified acceptance to any marshaled resource telling it the address of the second endpoint to connect to, sends a modified acceptance to the first endpoint that tells it the address of any marshaled resource, or of the second endpoint in the absence of any marshaled resource, to connect to, and leaves it up to the endpoints and marshaled resources to interact with the network to effect the connection through the network. The media manager can therefore provide centralized call control for substantially any network, and can treat all networks generically and leave it up to the endpoints to deal with the particulars of any specific network. Communications between multiple such telecommunications systems (8, 9) can also be effected thereby.
