Abstract
An apparatus and a method of optimizing voice quality on a network having end-points that are voice over Internet Protocol (IP) devices. Default parameters of the end-points are initialized. Network performance parameters are measured and evaluated to determine whether they signify that connection to the network is below a desired level of operation. If so, the default parameters of the end-points are re-set based on the evaluation. The adjustment may entail re-negotiating the CODEC connection and re-setting parameters for packet size and resetting parameters for jitter buffer size.

A method of voice performance improvement in a packet switched network, comprising:
- initializing an end-point device on a network, wherein the initializing comprises setting initial parameters affecting VoIP operation of the end-point device and performing at least one test to determine a favorable configuration for the end-point device;
- measuring at least one performance parameter of the network external to the end-point device;
- and
- evaluating whether the measured performance parameter indicates that a connection to the network is below a desired level of operation and, if so, transmitting a signal indicating that the connection to the network is below the desired level of operation.
An apparatus to effect voice performance improvement in a packet switched network, comprising:
- an initializer configured to initialize at least one initial parameter for an end-point device on a network and to perform at least one test to determine a favorable configuration for the end-point device;
- a measurer configured to measure at least one performance parameter of the network external to the end-point device;
- an evaluator configured to make a determination as to whether the at least one measured performance parameter indicates that a connection to the network is below a desired level of operation;
- and
- a transmitter configured to transmit a signal indicating that the connection to the network is below the desired level of operation.
