Hi all, recently i faced so probs with CCM 4.1 to register an IP Phone 7911 i got DBConfig Error but i with a 7970 it was fine so does this thing related to the fact that 7911G is not listed on CCM 4.1
You are always welcome my friend! This error is related to the fact that the IP Phone config is not entered in the CCM Database. For example, if I configure a phone with the Mac AAABBBCCCDDD but mis-enter it as AAABBBCCCDDE it will try to register but display the DBConfig Error.
From your first post, it sounded like perhaps the 7911 was not available as a valid IP Phone model from the Device Defaults page.
Hope this helps!
