ABSTRACT
This article presents information on routers that improve the performance of Voice over Internet Protocol (VoIP). First-generation VoIP adaptors brought simple and affordable Internet-based calling to the consumer and small office markets. VoIP can use a fair percentage of the upstream bandwidth of low-end broadband connections. Depending on the codec, VoIP can use a fair percentage of the upstream bandwidth of low-end broadband connections. That means it is liable to be interrupted by simultaneous traffic. A quality of service (QoS) router helps deliver better audio quality when other bandwidth-intensive applications are running simultaneously but at the expense of other applications' performance. Although QoS in the router will prioritize VoIP on the link to the Internet service provider, one should not expect voice packets to get priority in provider's network or on the Internet as a whole. The author states that voice quality was consistent across all the routers with built-in VoIP adaptors. With QoS enabled, it is better than mobile-to-landline but not quite as good as landline-to-landline.
