This hands-on guide supplies you with all the tools you need for VoIP service quality analysis, including explicit directions for: * designing subjective tests and interpreting results * selecting, extending, and applying speech distortion and multiple effects models * examining call set-up times for IP telephony * determining requirements for multimedia exchanges.
