Abstract
In a method and apparatus for measuring voice quality of an endpoint in a Voice-over-IP (VoIP) network, a plurality of network quality parameters are determined for the endpoint. A voice quality factor for the endpoint is determined in real time based on the network quality parameters.
Claims7
An endpoint apparatus in a Voice-over-IP (VoIP) network, comprising:
- a processor in the endpoint apparatus in the VoIP network for determining quality factors including packet delay, jitter, packet loss and signal level at the endpoint apparatus in the VoIP network and applying any needed correction factors to the quality factors, and
- a controller in the endpoint apparatus in the VoIP network for determining a voice quality factor for the endpoint apparatus in the VoIP network in real time as the endpoint apparatus is making a live call on the VoIP network based on the quality factors with correction factors received from the processor, wherein the voice quality factor for the endpoint apparatus is determined using a lookup table or an algorithm.
An endpoint apparatus in a Voice-over-IP (VoIP) network, comprising:
- a processor, and
- a controller having a lookup table stored therein, the lookup table being unique to the endpoint apparatus, wherein
- the processor inputs a plurality of network quality parameters, as modified by any correction factors, of the endpoint apparatus in the VoIP network into the lookup table, and
- the controller selects a predefined voice quality factor from the lookup table based on the inputs as the endpoint apparatus is making a live call on the VoIP network,
- wherein the plurality of network parameters comprise packet delay, jitter, packet loss and signal level, as modified by any correction factors.

A method of determining voice quality of an endpoint in a Voice-over-IP (VoIP) network, comprising:
- inputting data related to packet delay, jitter, packet loss and signal level of the endpoint, as modified by any correction factors, into a lookup table stored in the endpoint, and
- selecting a predefined voice quality factor from the lookup table based on the inputs as the endpoint is making a live call on the VoIP network.
