Abstract
An example communications system includes: a source device and a destination device; a Voice over Internet Protocol (VoIP) service, the VoIP service configured to support a voice call between the source device and the destination device over at least one of a wide-area IP network and a public-switched telephone network; wherein, for at least one leg in the voice call: an encoding device is configured to encode an analog audio stream to a digital audio stream according to one or more input parameters, the input parameters including variable input parameters; a receiving device is configured to send a quality indicator to the encoding device, the quality indicator representing the quality of the digital audio stream received at the receiving device; and the encoding device is configured to, at a feedback controller, determine updated variable input parameters for encoding a subsequent analog audio stream.
