A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : SIP Conventions for Connection Usage

SIP has many situations where a request can only be routed over an
existing connection. This can arise in cases with firewall or
network address translation (NAT) devices in the network path, over
both UDP and TCP. TLS is also affected when the user agent (UA) does
not have a certificate suitable for mutual TLS authentication. This
draft addresses how user agents and proxies need to behave to work in
these environments, and addresses keep-alive and DNS configuration
issues required for high reliability connections in situations where
the UA can form connections to the proxy but the reverse is not
generally true.
This work is being discussed on the sipping@ietf.org mailing list.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
