Hi all,

I forward this Internet-draft to the sipping list.
It discusses some issues regarding IPv4/IPv6 deployment and SIP interoperability.
Any comments?

Best regards,
Håkan Persson

A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title		: SIP Issues in Dual-stack Environments

The advent of IPv6 in addition to IPv4 makes hosts and servers dual-
stack. SIP communications can be used in both environments but there 
is little understanding what will happen if some nodes are dual-stack 
while others, presently the majority, is IPv4 only enabled. This 
document describes some scenarios and associated issues when dual-
stack users and servers try to communicate with IPv4 only hosts using 
SIP. It is not evident that interoperability is achieved, and if that 
is not the case, this would severely limit the usability of both SIP 
and IPv6.
