Need firmware update for SBG6580 modem - current firmware kills VOIP

Took the plunge and ordered Cox at home. Bought Motorola SBG6580 on Amazon because it has built in WiFi. Modem shipped with V. 3.3.x of firmware. Set up VOIP and everything works great.

Then after a billing snafu and reprovisioning, Cox rolls me back to 3.2.1 breaking my VOIP because 3.2.x has no means of disabling SIP ALG (called SIP Pass Through on the Moto). Now my VOIP is broken. http://www.voip-info.org/wiki/view/Routers+SIP+ALG

Level 1 and 2 support says no update yet. Love the router, just don't want to have to return it and run so many devices on my little desk to have cable modem + WiFi...

Come on COX, let's get a firmware update! Comcast is on 3.5.x and Charter is on 3.5.x also...
