RingCentral App Feature request: When using multiple speaker and microphone devices on a given system, callers can be unsure of whether their microphone is working, especially when leaving a voice mail to which the call recipient cannot verify the caller is being heard, perhaps if they have not selected the appropriate microphone device. In a similar case, a caller cannot hear a call recipient after placing a call if they have not selected the proper playback device.
To assist with this confusion, display the selected audio devices (speakers and microphone) within the dialpad on every call, and show a vertical or horizontal bar-style indicator of audio activity and its intensity (similar to what's found in Audio Settings in the RC Meetings app) as the caller or the call recipient are speaking. If some callers would find it distracting or unnecessary, allow the feature to be expanded/collapsed and for that selection to persist. If possible, allow callers to select different audio devices directly from the dialpad while on a call.
