Claim Text:
1. A method for determining the quality of experience for a multi-party conference call comprising: capturing values for a plurality of network characteristics for a conference call between at least three parties made using a multi-party conference call system in at least one of real-time and near real-time, wherein said plurality of network characteristics encompass at least parameters expressed in an E-Model R-Factor equation, wherein said multi-party conference call system utilizes a centralized focus component through which signals comprising the conference call are received from and sent to the at least three parties participating in the conference call, wherein the multi-party conference call system utilizes a Voice over Internet Protocol (VoIP); determining a quality of experience (QoE) that accounts for degradation effects of the centralized focus component for each party of the at least three parties that is currently receiving a signal from the centralized focus component as part of the conference call, wherein the determined QoE is represented as a corrected mean opinion score (MOS) perceived by the receiving party; and when the determined QoE of the conference call for the receiving party is below a predetermined threshold value, automatically and dynamically modifying a controllable parameter of the conference call to positively affect the determined QoE of the receiving party, wherein the controllable parameter of the conference call includes the codec being used for a receiving party, said modification of the controllable parameter further comprises:
