dcterms:description
In VoIP, the voice is transmitted over the IP networks in the form of packets. This way of voice transmission is highly cost-effective since the communication circuits need not be permanently dedicated to one connection; however, the communication band is shared by several connections. On the other hand, the utilization of IP networks causes some drawbacks that can result in the lower Quality of Service. This chapter evaluates impact of several factors on VoIP speech quality.
