Abstract
A system and method for providing service quality metrics related to the quality of service provided by a Voice over Internet Protocol (“VoIP”) network to voiceband modems or fax machines communicating over the VoIP network. The system utilizes a multi-state Markov model to evaluate the quality of service provided by the VoIP network and provides an assessment of the suitability of the network to carry voiceband data traffic.
