      "Cisco User Agent Session Initiation Protocol (SIP) 
    MIB module.  SIP is an application-layer signalling
    protocol for creating, modifying and terminating
    multimedia sessions with one or more participants.
    These sessions include Internet multimedia conferences
    and Internet telephone calls.  SIP is defined in 
    RFC 2543 (March 1999).  
    
    This MIB is defined for the management of SIP User 
    Agents (UAs).  A User Agent is an application which 
    contains both a User Agent Client (UAC) and a User 
    Agent Server (UAS).   A UAC is an application that 
    initiates a SIP request.  A UAS is an application that 
    contacts the user when a SIP request is received and 
    that returns a response on behalf of the user.  The 
    response accepts, rejects, or redirects the request.
    
    A SIP transaction occurs between a client and a server 
    and comprises all messages from the first request sent
    from the client to the server up to a final (non-1xx) 
    response sent from the server to the client.";

                                      with dns name pots.cisco.com.
