I have a IP Office 500 V2 with 5610 & 5620 that will just be paperweights in the morning. It's not always the same phones, the system randomly changes the top header from the user name to blocks with the extension number in the top line. The buttons show the correct programming, but it doesn't work. The users have been power cycling the phones to clear the issues.
All the phones are on their own network. The system is release 6.
