Achieving PSTN Voice Quality in VoIP
ثبت نشده
چکیده
Voice over Internet Protocol (VoIP) is being widely deployed to offer users low-cost alternatives for long-distance and international telephone calls. However, for users who are accustomed to the high-quality sound offered by traditional Public Switched Telephone Network (PSTN) service, VoIP voice quality often pales in comparison. Voice quality in VoIP networks widely varies as a result of several factors. This article will discuss how service providers can avoid service degradations in a VoIP network and deliver voice quality that is comparable to, or even exceeds, PSTN levels.

Voice over IP 15 . Voice over IP : Speech Transmission over Packet NetworksJ
The emergence of packet networks for both data and voice traffic has introduced new challenges for speech transmission designs that differ significantly from those encountered and handled in traditional circuit-switched telephone networks, such as the public switched telephone network (PSTN). In this chapter, we present the many aspects that affect speech quality in a voice over IP (VoIP) conve...

متن کاملVoice and Multi-Fractal Data in the Internet
In the Internet era there is a need to understand how traditional Public Switched Telephone Network (PSTN) services and the new Internet services can coexist. The best-effort based IP network will have to maintain the level of service that customers from the PSTN world expect. This study contributes to the traffic engineering of such a system by presenting an analytical model for integrating Vo...
متن کاملChoosing the UMTS Air Interface Parameters, the Voice Packet Size and the Dejittering Delay for a Voice-over-IP Call between a UMTS and a PSTN Party
In this paper we develop a methodology to set the VoIP application parameters (voice packet size and dejittering delay) and the UMTS air interface parameters in such a way that the quality of VoIP calls involving a UMTS party is ensured. We use analytical techniques to determine the delay and packet loss contributions of the various transmission stages crossed by the voice packet flow, and the ...
متن کاملUsing optimization to achieve efficient quality of service in voice over IP networks
For Internet Telephony to be a viable alternative to the Public Switch Telephone Network (PSTN), efficient and high quality communications are required. This paper proposes an optimization algorithm that selects parameters like coding scheme, packet loss bound, and maximum link utilization level in a Voice over IP (VoIP) network. The goal is to deliver guaranteed Quality of Service (for voice) ...
