Abstract

In a network, transmitted voice quality is improved by receiving voice packets from a remote voice coder, wherein the received voice packets have been encoded at a higher encoding rate. If a packet loss rate that exceeds a threshold loss rate is detected, a reduce encoding rate message is sent to the remote voice coder to cause the remote voice coder to encode future voice packets at a lower encoding rate. The voice packets may include a change encoding rate message in an error tolerant portion of the voice packet. The change encoding rate message may also include parity information for verifying the integrity of the message.
