RE: SIP Registration Problem - T49G
What version of firmware are you running? We have a demo unit that was shipped with T49-51.80.0.100, however, we could not get it to register either until we flashed T49-51.25.0.15, which appears to be a completely different firmware train.

I've asked our account rep what the difference between these 2 firmwares might be but have yet to receive a response.
