[Asterisk-Users] [OT] stupid firmware question...

[Chris Wade]

I know this is a really stupid question, but I just have to ask...

Where would I start if I wanted to try and develop my own firmware for a 
particular phone.  Namely, I want to try and 're-write' the SIP firmware 
for Cisco 7940's.  Any ideas?

just open-source the firmware for their phones? [* ducks head back
