A near end device is in a call (voice or video) over a communication link with a far end device. The near end device monitors constraints of the near end device, such as environmental noise at the near end device, latency between sequential data packets, signal strength or quality over the communication link, and energy level. The near end device detects when the near end device is having or is soon to have communication difficulty with the call due to one or more of the constraints. In response to detecting that the near end device is having or is soon to have communication difficulty with the call, the near end device communicates one or both of audible feedback and visual feedback to the far end device, notifying the far end device that the near end device is having or is soon to have communication difficulty with the call.
