asterisk users - Aug 2004 - Where to get latest SIP bootrom/firmware for Polycom IP500 phones?

I have these phones working well with Asterisk, thanks to 
	http://www.freedomphones.net/polycom/files
The code there is not the most current (and my Polycom Extranet login hasn't
gotten
updated yet to allow downloads).  Been waiting a while for their support folks
to
update the access.

If you know where I can get the 2.5.0 BootROM and 1.3.1 SIP code?

Thanks,
L.
