Voice Over Internet Protocol Phone

VOIP_Phone

• Voice Over Internet Protocol Phone : IP 네트워크를 사용한 음성 통화 프로그램
• L3 : IP / L4 : UDP / L7 : SIP, SDP, RTP
• 지원 코덱 : ALAW(8000), ULAW(8000), AMR-NB(8000), AMR-WB(16000), EVS(8000)

1) 기능

1) 양자 통화

1-1) End to End : 프록시 경유해서 통화

1-2) Peer to Peer : 피어끼리 직접 통화

2) 그룹 통화

2-1) 프록시에 첫 번째로 통화 시도한 참여자가 대화방을 생성

2-2) 대화방 생성 후 다른 참여자가 프록시에 통화 시도하여 해당 대화방에 참여

2-3) 모든 참여자가 대화방을 나가면 대화방 자동 삭제

2-4) 아직 참여자 제한 없음, 대화방은 하나만 생성 가능 > 외부 인터페이스에서 제어해야함, SIP 로는 제어 불가능

3) 녹취

3-1) 클라이언트

3-1-1) 내 목소리 녹취

3-1-2) 상대방 목소리 녹취

3-2) 프록시

3-2-1) 양자 통화 음성 합성 녹취

3-2-2) 그룹 통화 음성 합성 녹취

4) 프로그램

4-1) 우선순위 코덱 설정

4-2) 스피커, 마이크는 선택된 코덱에 따라 샘플링 레이트 결정 (8000 or 16000)

4-3) 볼륨 조절 (스피커, 마이크)

2) 설계

2-1) 구성도

2-2) 정상 호 Flow

2-3) 비정상 호 Flow 1

2-4) 비정상 호 Flow 2

2-5) 비정상 호 Flow 3

2-6) 비정상 호 Flow 4

3) SIP 메시지 예시

3-1) Group Call

3-1-1) Register
