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.
