Wired and wireless microphones cannot be used at the same time, and the wireless microphones have a
higher priority. Attempting to connect a wired microphone to a conference phone that has paired or
connected channels results in a warning to the user that the wired microphone is disabled. To solve this
problem, unpair any paired or connected wireless microphones before connecting a wired microphone.
