Description
Terminating network connections associated with communications sessions includes, for example, de-allocating associated TCP/IP address/port pairs at the operating system level, and de-allocating networking assignments at the application level if multiple application sessions are using a single, operating system level network connection. Enterprise Voice, Video, and Messaging Session Managers do not conduct media session; they conduct the session termination signaling. Endpoints and border elements conduct the media sessions and de-allocate those resources. However, sessions that do not receive a response from the far end may require the session manager to request termination of communication sessions.
