Enable Hot-Desk on all Phones

Having designated "Hot-Desk" phones is not an appropriate use of a license. IN many instances there is not enough designed visitor workstations to accommodate everyone. Yet, an employee with an assigned office / workspace may be out or traveling leaving an open workspace that can be utilized. Since the phone is permanently assigned a user profile the visiting employee cannot sign into the phone for their use. Eliminate the need to designate "Hot-Desk" phones and enable this feature on all phones.
