I imported several hundred phones/users into CUCM via BAT. On the User Template, I checked the box labeled "Default Telephone Number to Primary Extension" but it seems that it is ignoring this. The Telephone Number field is populated and the user is associated with their phone but the Primary Extension field isn't populated. I can go back to my Excel sheets, add the field in, use a concatenating formula to populate the field, and re-import, but I'm hoping someone knows of a better way. I could also export the users into a sheet, enter the info into the blank Primary Extension field, and re-import the users, but I'm looking for something more polished.
TL;DR Is there a way to make CUCM assign the Primary Extension on existing users in bulk that doesn't involve Excel sheets? A query-based change I'm missing or something like that.
