PERFORMANCE OF VoIP IN PRIVATE SYSTEMS
Our focus for this part of the chapter is to examine two studies conducted by Mier Communications Inc. on VoIP products. The general results of the first study are available from Mier Communications [MIER98].[3] The second study is also available from [MIER99] and [MIER99a][4]. Mier Communications can be reached at ed@mier.com. After we examine the first test, we then look at the new test, and compare the differences.
