looped back to an unbalanced output. By default, the flag is disabled.
Intercom When the Intercom flag is enabled, a technician at the base station can
communicate with a console over the line. The Base Station’s microphone is
connected to line output. When the flag is disabled, the microphone is
disconnected, but the speaker still remains connected to the receiver Path A.
