Method and apparatus for providing a configurable quality of service threshold for voice over internet protocol
First Claim
1. A method of connecting a telephone call from a user through one of a plurality of networks where one of the plurality of networks is an internet protocol network, comprising:
- determining a destination of the telephone call;
setting a first transmission factor and a first reception factor according to a predetermined minimum quality of service level requirement based on the destination of the telephone call;
receiving a second transmission factor and receiving a second reception factor responsive to the quality of service provided by the internet protocol network; and
connecting the telephone call through the internet protocol network if the second transmission factor is greater than the first transmission factor and the second reception factor is greater than the first reception factor, otherwise, connecting the telephone call through one of the plurality of networks other than the internet protocol network.

Abstract
A method of connecting a telephone call through one of a plurality of networks where one of the plurality of networks is an internet protocol network is provided. A first factor for an acceptable quality of service level is received from a user. A second factor responsive to the quality of service for the internet protocol network is determined. The telephone call is connected through the internet protocol network if the second factor is greater than the first factor, otherwise, the telephone call is connected through one of the plurality of networks other than the internet protocol network.

2. A method of connecting a telephone call through one of a plurality of networks where one of the plurality of networks is an internet protocol network, comprising:
-
receiving a threshold value; calculating a rating factor for the internet protocol network by subtracting a first value and a second value from a constant value, where the first value is 0 if the total one-way delay is less than 100 milliseconds, and, otherwise, the first value is calculated according to the following equation, in which Ta is the total one-way delay; - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)
