随着Voice Over IP服务的出现,Qwest Communications International及其它数家公司有望在确保声音网络可靠性的同时,帮助公司们降低在声音和数据方面的支出。 Qwest公司计划中的Voice Over IP服务将于下月在美国九个城市开通,小型企业用户和居民用户使用这项服务拨打州际电话的费用将是每分钟7.5美分。这些用户可通过拨打一个本地号码与该公司的光纤网络相联。即为了发送一个呼叫,用户将先拨打一个本地电话号码进入该网络,然后进入一个PIN,随后再拔打他所呼叫的对方的电话号码。这项服务可在一个共同的架构内使传统的声音网络和IP网络都能提供十分经济有效的、高质量的服务。
With the Voice Over IP service, Qwest Communications International and several others are expected to help companies reduce their voice and data expenditures while ensuring the reliability of their voice networks. Qwest’s planned Voice Over IP service, which will open in nine U.S. cities next month, will cost 7.5 cents per minute for small businesses and residential users to make interstate calls using this service. These users can connect to the company’s fiber optic network by dialing a local number. That is, in order to send a call, the user dials a local number, enters the network, enters a PIN, and dials the number of the other party he calls. This service enables traditional voice and IP networks to deliver cost-effective, high-quality services in a common architecture.
