1. Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes a set of managed objects that are used to
   manage Session Initiation Protocol (SIP) entities, which include User
   Agents, and Proxy, Redirect and Registrar servers.  The managed
   objects defined in this document are intended to provide basic SIP
   protocol management for SIP entities.  The management of
   application-specific or service-specific SIP configuration is out of
   scope.
