ABSTRACT:
This present invention provides a method, system, and apparatus for determining voice quality in a VOP network. The present invention implements the ITU-T E-model in a packet network. It implements the ITU-T E-model in a simplified approach using a straight-line estimate. Voice quality is estimated by assigning constant values to parameters in the ITU-T E-model and using data collected in a voice call.
