When listening to voicemails in the RingCentral iPhone app, the screen can time-out and auto-lock unless the phone is interacted with before the screen locks. We would like the iPhone's Auto-Lock to be ignored only when the playback of voicemails is occurring, allowing for the full message to be played uninterrupted and without intervention from the user. This is the normal behavior of the iPhone's built in voicemail playback.
