IP 语音(VoIP) 允许在分组数据网络上实现语音、传真信息与传统的数据包同时传输,可为各个层次的应用。 VoIP 的实现优势在于获得更低成本的传统语音与传真服务,同时用户还将受益于基于 VoIP 的,具有突破性的新型服务,如基于 web 的呼叫中心、协作式白板 (collaborative white boarding)、远程通信交换以及可提高个人效率的产品(如”跟踪”服务与统一消息处理) 等新型应用都是 VoIP 巨变的组成部分。 Voice over IP (VoIP) allows voice over packet data networks. Fax messages are transmitted at the same time as traditional data packets and can be used at all levels. The benefits of VoIP lie in the lower cost of traditional voice and fax services, while users will also benefit from groundbreaking new VoIP-based services such as web-based call centers, collaborative white boarding, remote New applications such as communications exchange and products that enhance personal productivity (such as “tracking” services and unified messaging) are part of the VoIP turmoil.
