A New Internet-Draft is available from the on-line
Internet-Drafts
directories.
This draft is a work item of the Session Initiation Protocol
Working Group of the IETF.
Title : Managing Client Initiated Connections in the
Session Initiation Protocol (SIP)
Author(s) : C. Jennings, R. Mahy
Filename : draft-ietf-sip-outbound-06.txt
Pages : 41
Date : 2006-11-26
The Session Initiation Protocol (SIP) allows proxy servers
to
initiate TCP connections and send asynchronous UDP
datagrams to User
Agents in order to deliver requests. However, many
practical
considerations, such as the existence of firewalls and
Network
Address Translators (NATs), prevent servers from
connecting to User
Agents in this way. This specification defines behaviors
for User
Agents, registrars and proxy servers that allow requests
to be
delivered on existing connections established by the User
Agent. It
also defines keep alive behaviors needed to keep NAT
bindings open
and specifies the usage of multiple connections.

Send a message to:

In the body type:
"FILE
/internet-drafts/draft-ietf-sip-outbound-06.txt".
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.
