Patent ID: 8804575

Claim:
A method comprising: monitoring a voice over packet media stream sent from a first voice over packet endpoint to a second voice over packet endpoint for impairments at the second voice over packet endpoint, the voice over packet media stream sent from the first voice over packet endpoint to the second voice over packet endpoint without passing through a central entity; computing voice over packet quality metrics based on the impairments at the second voice over packet endpoint; sending the voice over packet quality metrics from the second voice over packet endpoint to a session peer; when a threshold is crossed for the voice over packet quality metrics, sending an event notification to the central entity; preliminarily altering one of packet redundancy levels or forward error correction settings for the voice over packet media stream based on the event notification at the central entity; and changing, from the central entity in response to the central entity receiving the event notification, media characteristics of the voice over packet media stream in relation to the impairments by signaling at least one of the first or second voice over packet endpoints from the central entity.
