Thank you Mohammed! That information pointed me in the right direction and I was able to get the phone to register. Hopefully, this will help everybody else out. The key here was that the digest username HAS to be the same as the DN.
Mohammed, thanks for the response. I just saw this and am looking in RTMT at the traces. Which service should I be looking at and which trace file type? I'm assuming I should be looking at UCM traces? Thanks
