These resources are NOT to be passed on for commercial gain in any format. These are the result of years of personal tinkering and experimentation to open up a BCM50 for home and personal use or experimenting, following Avaya announcing their termination of support or licensing of the same. After a purchase of a SIP License that didn't function as expected, the drive was on. None of the code contained herein was derived from any original source code of Nortel or Avaya. It was the result of endless debugging and examining of running code. PPC (Motorola Power PC) code is also significantly easier to disassemble to watch the flow of oddly... Enjoy.
