We are trying to change most of our phones over to VOIP. The problem is the 9630 phones come right up without a hitch but the 9620 phones do not. They get stuck discovering the clan which makes me think there are some files that need to be added to the network. But how can that be if they suposedly use the same files? I did catch a quick message as it was booting up "invalid file hb96xxua2_00.bin" Then it asks for ext. and password after entering that it gets stuck discovering the clan address' Thanks in advance.
