편견 없는 언어

본 제품에 대한 문서 세트는 편견 없는 언어를 사용하기 위해 노력합니다. 본 설명서 세트의 목적상, 편견 없는 언어는 나이, 장애, 성별, 인종 정체성, 민족 정체성, 성적 지향성, 사회 경제적 지위 및 교차성에 기초한 차별을 의미하지 않는 언어로 정의됩니다. 제품 소프트웨어의 사용자 인터페이스에서 하드코딩된 언어, RFP 설명서에 기초한 언어 또는 참조된 서드파티 제품에서 사용하는 언어로 인해 설명서에 예외가 있을 수 있습니다. 시스코에서 어떤 방식으로 포용적인 언어를 사용하고 있는지 자세히 알아보세요.

이 번역에 관하여

Cisco는 전 세계 사용자에게 다양한 언어로 지원 콘텐츠를 제공하기 위해 기계 번역 기술과 수작업 번역을 병행하여 이 문서를 번역했습니다. 아무리 품질이 높은 기계 번역이라도 전문 번역가의 번역 결과물만큼 정확하지는 않습니다. Cisco Systems, Inc.는 이 같은 번역에 대해 어떠한 책임도 지지 않으며 항상 원본 영문 문서(링크 제공됨)를 참조할 것을 권장합니다.

소개

이 문서에서는 4가지 서로 다른 통화 라우팅 시나리오와 일치하는 디버그가 포함된 Cisco Unified SIP Proxy(CUSP)의 샘플 CLI 및 GUI 컨피그레이션에 대해 설명합니다.

사전 요구 사항

요구 사항

Cisco에서는 이러한 주제에 대한 기본적인 지식을 얻을 것을 권장합니다.

  • SIP(Session Initiation Protocol)
  • Cisco Unified SIP Proxy(CUSP)

사용되는 구성 요소

이 문서의 정보는 CUSP를 기반으로 합니다.

이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다.이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다.현재 네트워크가 작동 중인 경우, 모든 명령어의 잠재적인 영향을 미리 숙지하시기 바랍니다.

구성

이 섹션에서는 네 가지 통화 라우팅 시나리오의 컨피그레이션에 대해 설명합니다.

참고:이 섹션에 사용된 명령에 대한 자세한 내용을 보려면 Command Lookup Tool(등록된 고객만 해당)을 사용합니다.

시나리오 1

통화 흐름:IP Phone 1 — CME — SIP — CUSP — SIP — CUCM — IP Phone 2

CUSP를 통해 Cisco CUCM(Unified Communications Manager)에 등록된 IP Phone 2에 연결하려면 CME(CallManager Express)에 등록된 IP Phone 1에서 408 2 202 2 2102로 전화를 겁니다.

CME는 이 시나리오에서 PSTN(Public Switched Telephone Network)의 역할을 합니다.

  1. CME에서 SIP INVITE가 CUSP로 전송됩니다.

    참고:CUCM과 같은 일부 디바이스는 요청을 처리하기 전에 요청의 URI(Uniform Resource Identifier)를 검증합니다. 즉, 이 작업을 허용하려면 최종 디바이스가 FQDN(Fully Qualified Domain Name)으로 구성해야 합니다.

    CUCM의 경우 CUCM > System > Enterprise Parameter > Clusterwide Domain Configuration > Cluster Fully Qualified Domain Name은 서버 그룹 이름과 같아야 합니다.

시나리오 2

통화 흐름:IP Phone 1 — CUCM — SIP — CUSP — SIP — CME — IP Phone 2

IP Phone 1에 연결하려면 IP Phone 2에서 Dial 202 2222를 먼저 사용해야 합니다. 408은 사전 정규화 접두사로 사용해야 합니다.

CME는 이 시나리오에서 PSTN으로 작동합니다.

  1. CUCM에서 SIP INVITE가 CUSP에 옵니다.

통화 흐름: IP Phone 1 — CME 1 — SIP — CUSP — SIP — CME 2 — IP Phone 2

IP Phone 1에 연결하려면 IP Phone 2에서 4444로 전화를 겁니다. 이 번호는 415 240 444로 변경되고 IP Phone 1에 연결되면 정상화가 이루어집니다.

CME 2는 이 시나리오에서 UC520이며 CME 1은 PSTN 역할을 합니다.

  1. SIP INVITE는 CME 2(UC520)에서 CUSP로 전송됩니다.
