[Henry Lowe <hlowe@omg.org>]

This adresses a subject we have discussed in the past 
and I thought might be of interest to TRP.  

Note: I have only read the precis below, not the full 
paper.

Have a good Thanksgiving for those of you in US.

	Title		: SIP Traversal through Residential and Enterprise NATs 
                          and Firewalls
	Author(s)	: J. Rosenberg, H. Schulzrinne
	Filename	: draft-rosenberg-sip-entfw-00.txt
	Pages		: 15
	Date		: 21-Nov-00
	
In this draft, we discuss how SIP can traverse enterprise and
residential firewalls and NATs. This environment is challenging
because we assume here that the end user has little or no control
over the firewall or NAT, and that the firewall or NAT is completely
ignorant of SIP
