Voice over WAN refers to the transmission of voice communications over a wide area network, typically using internet protocols. This allows for voice communication to be extended beyond local networks, enabling individuals or organizations to communicate over long distances.
Voice over WAN is commonly implemented using VoIP (Voice over Internet Protocol) technology, which digitizes voice signals into data packets that can be transmitted over the Internet or other WAN connections. VoIP offers several advantages, including cost savings, flexibility, and the integration of voice communication with other digital services.
However, there are also challenges associated with voice-over WAN, including potential issues with call quality, latency, and reliability. These challenges can be mitigated using quality of service (QoS) mechanisms, proper network design, and the use of dedicated voice channels or bandwidth optimization techniques.
Overall, voice-over WAN has become increasingly popular as organizations seek to streamline their communication infrastructure and leverage the benefits of digital voice technology.
