2-way audio not working with Spotlight Cam Battery

When I get a motion alert, or when I go into Live View, I am not getting my audio from the app to the camera. When I open the view, I un-mute the audio at the camera side and I can hear the audio there, but when I click the green phone icon to speak, it does not go through. Later, when I playback the video, my audio that I attempted can be heard. But the person at the camera does not hear the audio live.
