초록

최근 컴퓨팅 패러다임의 변화와 다양한 서비스를 지원하기 위한 VoIP 기술이 재조명 받고 있다. 본 논문에서는 VoIP 기반의 음성 보안 서비스를 지원하기 위한 소프트웨어 PBX인 오픈소스 Asterisk와 하드웨어 플랫폼, 그리고 모바일 단말기간의 시스템 설계 및 구현하였다. 특히 하드웨어 플랫폼에서는 싱글보드에서부터 가상화를 위한 XenServer 기반의 서버들을 이용한 다양한 플랫폼을 지원하도록 설계하였다. 그리고 이를 기반으로 한 네트워크 트래픽의 지연 테스트와 음성 보안 테스트를 통해 검증하였다.

Recently, the computing paradigm has been changing and VoIP technology is being revisited to support various services. In this paper, we have designed and implemented the system of software PBX open source Asterisk, hardware platform, and mobile devices to support secured voice service based on VoIP. Specially, we designed the various platform from single board to servers based on XenServer in hardware platform. And we verified the delay test of network traffics and the secured voice communication test based on this platform.
