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


	Title		: Early Media Issues and Scenarios

Once an INVITE is sent, an UAC should be able to handle incoming 
media at anytime. Hence, a SIP terminal should be able to support 
early media. However, there are some issues with the way session 
descriptions (SDP) in provisional responses are handled, optional 
use of resource reservation, complexity introduced by forked INVITEs 
and interactions with NAT/Firewall traversal. This draft discusses 
some of these issues along with related IP-PSTN inter-working 
scenarios.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-sen-sip-earlymedia-00.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
