Abstract:	隨著科技的發展，網路技術越趨成熟，使得網路服務的型態已逐漸改變，在使用電路交換的時代，人們只能透過簡訊及電話來傳達訊息，現在已演進為封包交換的網路，不但可以進行語音通話，更可以進行多媒體資料的傳輸,因此透過影像傳輸技術，有聲無影的時代也即將告別。 IP多媒體子系統有電路交換及封包交換系統的優勢，所以，我們將實做出IP多媒體子系統客戶端的程式, 包括基本的語音影像通話功能，及時訊息及使用者狀態顯示功能，而在本篇的論文中，將著重於及時語音及影像通話引擎的實做,並且在微軟的作業平台上，盡可能避免掉語音通話中致命的議題-回音，使得通話品質可以維持一定的水準，且能維持通話的穩定性。 With the development of the network technology, it drives the internet services change intensely. In the public switched telephone network (PSTN) age, people only could use the SMS and dial a telephone to communication. Nowadays, it can offer multimedia data transmission via packet switch network. People not only could make a voice call but also make a video call. Therefore, the age of multimedia will coming. Since the IP Multimedia Subsystem (IMS) has the advantage of the cellular system and internet system. We would like to realize the IMS client. Including basic voice and video call, instant message, and presence function. In this paper, we will focus on the voice and video communication engine implementation that using the open source library. And keep the echo-free in the Microsoft Operation System in the VoIP. As a consequence, we hope to have a good quality of voice. And keep the stable in the every communication.
