Abstract

This document defines a Dynamic Host Configuration Protocol (DHCP-for-IPv4) option that contains a list of domain names or IPv4 addresses that can be mapped to one or more Session Initiation Protocol (SIP) outbound proxy servers. This is one of the many methods that a SIP client can use to obtain the addresses of such a local SIP server.

Abstract

   This document defines a Dynamic Host Configuration Protocol

   (DHCP-for-IPv4) option that contains a list of domain names or IPv4

   addresses that can be mapped to one or more Session Initiation

   Protocol (SIP) outbound proxy servers.  This is one of the many

   methods that a SIP client can use to obtain the addresses of such a

   local SIP server.

1.  Terminology

        DHCP client: A DHCP [1] client is an Internet host that uses

             DHCP to obtain configuration parameters such as a network

             address.

        DHCP server: A DHCP server is an Internet host that returns

             configuration parameters to DHCP clients.

        SIP server: As defined in RFC 3261 [2].  This server MUST be an

            outbound proxy server, as defined in [3].  In the context of

            this document, a SIP server refers to the host the SIP

            server is running on.

        SIP client: As defined in RFC 3261.  The client can be a user

            agent client or the client portion of a proxy server.  In

            the context of this document, a SIP client refers to the

            host the SIP client is running on.

2.  Introduction

   The Session Initiation Protocol (SIP) [2] is an application-layer

   control protocol that can establish, modify and terminate multimedia

   sessions or calls.  A SIP system has a number of logical components:

   user agents, proxy servers, redirect servers and registrars.  User

   agents MAY contain SIP clients, proxy servers always do.
