ONFIGURATION
The two endpoints open one or more logical channels between them for
transporting media streams. (The logical channels are specified by IP address plus
port number.)
These channels are closed when the communication is over.
Finally, either endpoint in communication can release resources by sending a
release complete message.
The endpoints each send a Disconnect_Request (DRQ) to their own gatekeepers,
which will confirm or reject the request. The gatekeepers, however, may send a
DRQ to the endpoints. In this case, the endpoints can only confirm the request.
Figure 684 shows the call setup flow and disconnection flow in which gatekeepers
are involved.
