- Cisco CUCM(Unified Communications Manager)
사용되는 구성 요소
이 문서의 정보는 다음 소프트웨어 버전을 기반으로 합니다.
이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다. 이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다. 네트워크가 작동 중인 경우 모든 명령의 잠재적인 영향을 이해해야 합니다.
구성
1단계. callmanager.pem 인증서를 VG224에 복사합니다(아래 컨피그레이션에서 SECURE 신뢰 지점으로 참조).
2단계. MAC 주소가 FastEthernet0/0(바인드 인터페이스)인 VG224에 주체 이름으로 마지막 10자리만 사용하는 자체 서명 인증서를 생성합니다.
3단계. vg-cert를 통화 관리자 트러스트로 CUCM에 복사하고 CUCM을 다시 시작합니다.
이 정보는 VG224에 필요한 인증서 구성에 제공됩니다.

팁: 명령 참조 안내서
참고: 주의 사항 CSCti08882 때문에 보안 VG224 아날로그 폰에서 보안 IP 폰으로 전화를 걸 때 잠금 아이콘이 표시되지 않습니다
다음을 확인합니다.
