Rating voice quality in practice

One approach is to occasionally ask IP phone users to indicate how the quality of their call was at the end of the call ⇒ MOS scoring!

Another is exemplified by Susan Knott, global network architecture for PricewaterhouseCoopers:

“But I’ve found that if my vice president of finance can talk to my CIO [over a VoIP connection], and they both say the quality of the connection is OK, then I say that’s good enough.”

Phil Hochmuth, “Quality question remains for VoIP”, NetworkWorld, Vol. 19, Number 40, October 7, 2002, pp. 1 and 71, quote is from page 71

[slide468] Susan Knott from PricewaterhouseCoopers said, the quality is good if my vice president of finance can talk to my CIO over a VoIP connection. ANd they both say the quality is okay. That's good enough. As measured by user happiness of your boss. Now you might say, is that a good idea? Well, at Blue Cross Blue Shield, a large healthcare organization in New York State, the CEO of the company has a voice conference and multimedia conference with his employees Monday, Wednesday, and Friday every week. You can bet that the voice operations groups make sure that the quality of that session is very, very high. And they actually schedule their resources to ensure that that voice conference with all of their employees is going to have very high quality. Yes. So you can achieve high quality, but it may mean you have to schedule other things not to happen at those times.
