General Purpose Outputs
Two General Purpose Outputs are used to indicate the Wait and Talk states.
Once the PTT is active the “Wait” output will assert while the system establishes the necessary audio paths, checks for zone availability
and plays the chime (if selected). The “Talk” output will assert once the audio path is live.
