摘要

VoIP網路電話技術始於1995年以色列的VocalTec公司推出的軟體IP電話“Internet Phone”，指在以IP為網路層協定的網際網路中進行語音傳送的業務。其最大的好處就是通話成本非常便宜，幾乎是一種完全免費的通訊概念。

在發展初期，人們首先嘗試讓二台PC傳送語音，這是VoIP技術應用的開始。之後發展意識到僅在PC之間通話是遠遠不夠的，於是開始考慮將Internet和已有的PSTN網路相結合，這樣就出現了Phone-to-Phone和PC-to-Phone等多種VoIP網路電話業務，VoIP網路電話從此進入了迅速發展的時期。

在個人和家庭網路用戶市場，因為大多使用浮動IP的問題難以解決，VoIP網路電話難以建立有效地收費模式。企業則擁有自己內部的Intranet網路，IP由內部獨立配發，即使企業運作每天有龐大地移動商業通訊需求，VoIP網路電話仍能滿足此功能，又能降低通訊成本，可說非常適合建置此套系統。

若在企業和其伙伴和客戶之間，利用Enterprise Exchange交換機予以連接，彼此就可以利用VoIP網路電話系統彼此互連，進而創造網路效果，在原本頻繁的需求中，創造出網路電話的價值，此外，若遇到斷電或是網路壅塞時，可以和舊式PSTN電話連接，結合其穩定性佳的優點，並創造出真正能夠加值收費的應用模式。

Abstract

Idea of VoIP (Voice over IP) is developed from the software “Internet Phone” come from VocalTec company in 1985. It transfers voice packages in the layer of internet protocol. The most benefit is to save cost of communication, closely to free dialing.

At the beginning, People tried to connect two personal computers. After that, they knew that it’s not enough and concerned connecting the internet phone with PSTN system. Then we have the Phone-to-Phone and PC-to-Phone VoIP systems. The development is accelerating.

In the individual and home internet market, it’s hard to build up a useful business model to charge fees because of floating IP. Corporate has intranet and fixed IP system. Fixed IP is important to talk between the IP mobile and handle the huge amount of communication.

In the thesis, we suggest to moderate an Enterprise Exchange to make corporate connected with its partners and customers. They can contact by VoIP system and enjoy communication with lower cost. This model help develop internet effect and connect with PSTN when the internet doesn’t work. We hope that it’s really valuable business model in VoIP.
