近年來網路的蓬勃發展，各式各樣的家庭網路與辦公室網路應用逐漸增加，像是照明系統、家電控制等相關應用。為了讓應用更多元化，包括定位資訊或蒐集室內資訊的應用等，感測網路的使用也愈顯重要。
網路的發展所帶來的另外一種應用，則是智慧家庭的興起，我們可以在家庭網路的環境底下，透過感測的資訊，可以根據不同的使用者提供相對應的服務應用，於是乎情境感知的應用服務也愈加重要。
隨著科技的發展以及網路的普及，寬頻的家庭使用率已經逐漸上升，而網路電話(VoIP)的價格低廉，使得越來越多的業者將普通的電信網路換成VoIP的網路服務，其通話費率大幅降低，更加突顯網路電話價格低廉的優點，在未來不久的時代，VoIP將有可能完全取代舊有的傳統電信網路，由於VoIP的服務是基於IP網路上，於是在應用上可提供多樣化的服務。
結合VoIP與智慧家庭網路，我們可以基於家庭網路所提供的情境資訊，根據不同的使用者提供其個人化的服務，於是我們將建置一個具情境感知機制在VoIP的環境底下，以達到自動化的轉接服務，將資訊轉換成有意義的資料，再去控制會話初始協定(SIP)的網路通訊系統。

With the rapid development of network technology, various applications of digital home and office networking are increasing, like lighting system and household appliance control. To make the applications such as mobile applications and indoor information collection applications diversified, the use of sensor network shows its importance.
The rise of the smart home is another kind of application brought in development of the network. By means of the detected information under the environment of home’s network, we can offer corresponding service applications according to different users. It becomes more important about context-aware services.
Popularization of network with the development of science and technology, wide-band network rate of utilization of family already rise gradually. With the cost down of VoIP, more and more companies change the ordinary telecommunication network into a network service of VoIP. Its conversation rate is reduced by a wide margin and makes it more conspicuous for the cheapness of network telephone. In the era soon in the future, VoIP will totally replace some old traditional telecommunication networks probably. Because the service of VoIP is based on the IP network, it can offer diversified services in using.
Integrating VoIP and smart home network, we can offer individualized services according to different users based on the situation information that home network offered. In order to reach the switching service of automation, we have to provide context-aware mechanism under the environment of VoIP. Change the information into the meaningful materials and then go to control SIP network communication system.
