To remotely control the PTT button on the user terminal, [emit](https://socket.io/docs/client-api/#socket-emit-eventName-%E2%80%A6args-ack) a 'ptt' event on the socket.io connection. The event parameter must be a boolean value that represents the desired state of the button (true for pressed, false for released). The terminal will generate a response once the button has been switched to the desired state. The terminal will automatically release the PTT button if the socket.io connection is terminated.
Note: If the microphone input on the speaker-mic is electrically disconnected while the physical PTT button is released (usually the case), remotely activating the PTT button will not activate the physical microphone.
