I'm doing ok, thank. Very busy with work, school and family, but I am 
keeping an eye on the HRI work. I still have my Uniden box waiting for 
me to be investigated... but no time for that. Right now, I am just 
curious about what OS is my Azacall 200 VoIP box running.

This won't be easy. The firmware is downloaded by the device from a TFTP 
server at boot time. I need to wait for a new version to be released.

Thanks,
