인터넷 이용자 수의 급격한 증가와 인터넷 서비스 보급의 대중화에 따라 인터넷에서 최고의 미래가치를 갖는 기술로 VoIP(Voice over IP)기술이 부각되고 있다. 현재 가장 활발하게 연구되고 있는 VoIP 기술로는 H.323과 SIP(Session Initiation Protocol)가 있다. SIP는 사용자간에 멀티미디어 세션을 생성, 수정, 해제하는 응용 계층의 시그널링 프로토콜로서, H.323에 비해 단순한 구조를 가지고 있고 새로운 부가 서비스를 추가하기가 쉽다는 장점이 있어서 앞으로 많은 사용이 예상된다. 비록 SIP가 차세대 네트워크 및 서비스에 이용될 전망이지만, H.323 기반의 기존 서비스를 무시할 수 없으므로 H.323 기반의 서비스를 사용자에게 투명하게 제공하면서 SIP 기반 구조로의 변환 모색이 필요하다 따라서, 본 논문에서는 SIP와 H.323간의 연동 서비스를 제공하는 SIP-H.323 Translator의 설계에 대해 기술하고자 한다.
