I deleted an IP phone from one of our 3300 MXe III systems using the User and Device Configuration form. However, when I attempt to add the same device back into the system, I get an error indicating that I have no available licenses. When I check the License and Option Selection form, I see that the Locally Allocated and Locally Consumed both = 37, with Available for Allocation = 0. How do I free up the license from the device that was deleted from the system?
