Abstract

This document defines a Dynamic Host Configuration Protocol version 6 (DHCPv6) option that contains a list of domain names or IPv6 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 version 6

   (DHCPv6) option that contains a list of domain names or IPv6

   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

   This document uses the DHCP terminology defined in [1].

   A SIP server is 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 outbound SIP proxy

   server is running on.

   A SIP client is defined in RFC 3261 [2].  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.

   This document specifies two DHCPv6 options [1] that allow SIP clients

   to locate a local SIP serve...
