I have to change this value from "false" to "true" for about 75 phones in my environment.
Is there a way to do that without touching and resetting every phone by hand?
I just had a look to bulk administration , but it seems as if there is no way to change this field.
Has anyone a hint or idee on this problem?
Look at Phones > Update Phones. The Excel spreadsheet does not contain every setting available!
You use a Phone Template when adding phones initially to set these things. The spreadsheet contains the values that unique to each phone (MAC, description, Owner User ID, etc) and the Phone Template sets everything else.
