CME/CUE You have entered an invalid phone number.

Running CME and CUE on a 3925 router.

Recently company phone number changed, to make extension number same as last digits of DID,  all phone’s extensions changed too, from 4 digits to 3 digits.

Then Auto attendant didn’t work, couldn’t reach extension from AA script with message “You have entered an invalid phone number.”.



Reason:    there was no user and user extension in CUE(not CME),

Solution:  after creating several users in CUE, it started to work again.
