Hi!

A while ago the SIP Forum IPv6 working group produced a document on the impact of IPv6 on IPv4-only SIP implementations, in order to inform developers about issues found at the SIP Forum  SIPit events and in real life tests in other places. We contributed this document to the IETF but as it did not really match the IETF documentation flow, we decided to finally publish it as a SIP Forum document.

You can find it here:
http://www.sipforum.org/component/option,com_docman/task,cat_view/gid,129/Itemid,261/

This document captures potential impacts to IPv4 SIP implementations when interworking with IPv6 SIP implementations. Although some amount of interworking translation will occur at the network and application layers, an IPv4 SIP application may still encounter a SIP message with some IPv6 values in it, resulting in unforeseen error conditions. Such potential scenarios will be identified in this document so that SIP application developers can define solutions to handle these cases. Note, this document is not intended to be an exhaustive list, rather to provide an overview of some of the more commonly encountered potential scenarios.

A big thank you to everyone involved in the process and especially to my co-authors Carl Klatsky and Gonzalo Salgueiro!

We will continue testing at the SIPit event in New Hampshire in September. If you haven’t registred yet, it’s high time. Go to
