    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."
