    DESCRIPTION
       "Session Initiation Protocol (SIP) Server MIB module.  SIP is an
        application-layer signaling 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 3261 (June 2002).

        This MIB is defined for the management of SIP Proxy, Redirect,
        and Registrar Servers.



        A Proxy Server acts as both a client and a server.  It accepts
        requests from other clients, either responding to them or
        passing them on to other servers, possibly after modification.

        A Redirect Server accepts requests from clients and returns
        zero or more addresses to that client.  Unlike a User Agent
        Server, it does not accept calls.

        A Registrar is a server that accepts REGISTER requests.  A
        Registrar is typically co-located with a Proxy or Redirect
        Server.

        Copyright (C) The IETF Trust (2007).  This version of
        this MIB module is part of RFC 4780; see the RFC itself for
        full legal notices."

    DESCRIPTION



       "This object reflects the default mode of operation for the
        Proxy Server entity.

        A stateless proxy is a logical entity that does not maintain
        the client or server transaction state machines when it
        processes requests.  A stateless proxy forwards every request it
        receives downstream and every response it receives upstream.  If
        the value of this object is stateless(1), the proxy defaults to
        stateless operations.

        A transaction stateful proxy, or simply a 'stateful proxy', is
        a logical entity that maintains the client and server
        transaction state machines during the processing of a request.
        A (transaction) stateful proxy is not the same as a call
        stateful proxy.  If the value of this object is
        transactionStateful(2), the proxy is stateful on a transaction
        basis.

        A call stateful proxy is a logical entity if it retains state
        for a dialog from the initiating INVITE to the terminating BYE
        request.  A call stateful proxy is always transaction stateful,
        but the converse is not necessarily true.  If the value of this
        object is callStateful(3), the proxy is call stateful."
