All of a sudden it worked. I did not do anything different. After I downgraded the firmware it auto upgraded back to build 5069 during one of the failed attempts. After several more failed attempts, it just worked. It took about 6-7 hours total to set this up. This is my 1st experience with this device, and I have set up a SIP account on our AVAYA system at work with less hassle. This is not user friendly and I don't think I will be recommending this to anyone else.
