Zero Config main page
Phone users can dial service code **766* + room number to set the room number, and dial service code **766# to hear
the room number announcement. When the hotel room number is already in use, phone users should dial service code
**766* + keypad password + room number + # to reset the room number.
Phone users can dial **82# to enable the UCM zero-configuration number selection process. The UCM sends the room
number as the selection number. After receiving the request, the UCM delivers the configuration and sets the room
number as the preferred account to complete the selection process.

Important considerations
1. The extension number cannot be selected when the account number in UCM exceeds the upper limit, and the upper limit of
the extension number must be specified.
2. The extension number selection function is not enabled or cannot be selected after the pick extension number selection
period has expired.
3. The UCM must contain the template of the target phone and the configuration related to the account in the template.
4. In zero configuration, the total of the selected numbers of extension numbers can be repeatedly selected by multiple phones
on the premises, however, it should not exceed the maximum number of registered accounts (concurrent number).
