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

VXML(Voice Extensible Markup Language)은 W3C(World Wide Web 컨소시엄)에서 정의한 표준입니다.VXML은 합성된 음성, 구어 인식, DTMF 숫자 인식 및 음성 녹음 기능을 제공하는 오디오 대화 상자를 만들도록 설계되었습니다.VXML 서버 및 클라이언트는 잘 알려진 HTTP 프로토콜을 사용하여 VXML 문서와 페이지를 교환합니다.

Cisco CVP(Voice Portal)는 전화를 통해 액세스할 수 있는 지능적이고 대화형 음성 응답(IVR) 애플리케이션을 제공합니다.CVP 구축에는 세 가지 유형이 있습니다.

독립형 서비스
CVP 통화 제어
통화 대기열 및 호전환

합성된 음성, 음성 인식 또는 DTMF 숫자 기능은 TTS(Text-to-Speech) 및 ASR(Automatic Speech Recognition) 서버에서 제공합니다.Cisco IOS® VXML 게이트웨이는 MRCP(Media Resource Control Protocol)를 사용하여 TTS 및 ASR 서버와 통신합니다. MRCP의 두 가지 버전(RFC 4463)은 MRCPv1(RTSP를 통한 MRCP) 및 MRCPv2(MRCP over SIP)입니다.

이 문서에서는 MRCPv1 TTS 또는 ASR 서버를 사용하는 독립형 서비스 구축에서 CVP에 대한 Cisco IOS Voice XML Gateway의 통화 흐름에 대해 설명합니다.샘플 약국 애플리케이션이 CVP VXML 서버에 구축되었습니다.

통화 흐름 예

이 섹션에서는 이 컨피그레이션 예제의 결과로 나타나는 통화 흐름에 대해 설명합니다.

ISDN 통화가 T1 PRI 3/0을 통해 PSTN/VXML 게이트웨이에 도착합니다.
IOS 게이트웨이는 이 통화의 인바운드 다이얼 피어로 POTS 다이얼 피어 1을 매칭합니다.
IOS Gateway는 통화 제어를 다이얼 피어 1과 연결된 약국 서비스로 전달합니다.
약국 서비스와 연결된 CVP VXML/TCL 스크립트는 VXML 서버에 HTTP GET 요청을 전송합니다.
VXML 서버는 200 OK 응답을 반환합니다.이 응답에는 VXML 문서 또는 페이지가 포함되어 있습니다.
IOS 게이트웨이가 VXML 문서를 실행합니다.
VXML 문서에서 오디오 프롬프트의 URL을 지정하면 IOS 게이트웨이가 오디오 파일을 다운로드하고 프롬프트를 재생합니다.
VXML 문서에서 오디오 프롬프트에 대한 텍스트를 지정하면 IOS 게이트웨이는 rtsp://10.86.177.39/synthesizer(TTS 서버)으로 RTSP 세션을 설정합니다. RTSP 세션이 설정되면 RTSP ANNOUNCE 요청을 사용하여 게이트웨이 및 TTS Server가 SPEAK, SPEAK-COMPLETE 등의 MRCP 메시지를 교환합니다.

TTS 서버는 RTSP 설정 요청의 "Transport" 헤더에 있는 게이트웨이가 제공한 IP 주소 및 UDP 포트 번호로 G.711ulaw RTP 오디오 스트림을 전송합니다.
VXML 문서가 DTMF 숫자 및 음성 단어를 인식하도록 게이트웨이를 지정하는 경우 IOS 게이트웨이는 rtsp://10.86.177.39/recognizer(ASR 서버)으로 RTSP 세션을 설정합니다. RTSP 세션이 설정되면 게이트웨이 및 ASR 서버는 RTSP ANNOUNCE 요청을 사용하여 DEFINE GRAMMAR, COMPLETE, RECOGNITION, RECOGNITION-COMPLETE 등의 MRCP 메시지를 교환합니다.

IOS VXML 게이트웨이는 RTSP 200 OK 응답의 SDP에서 ASR이 제공하는 IP 주소 및 UDP 포트 번호로 G.711ulaw RTP 오디오 스트림을 전송합니다.IOS VXML 게이트웨이는 PSTN 사용자가 RTP-NTE 이벤트로 입력한 숫자를 ASR 서버로 전송합니다.
VXML 문서를 실행한 후 게이트웨이는 VXML 문서 또는 페이지의 <submit> 태그에 지정된 대로 HTTP POST 요청(매개 변수 집합 포함)을 보냅니다.
6 - 10단계는 서버에서 전송하는 각 VXML 문서에 대해 발생합니다.
VXML 응용 프로그램은 호출자에게 제공된 서비스를 마치면 <form> 요소 내에 <exit/> 태그가 있는 VXML 문서를 보냅니다.
IOS 게이트웨이는 TTS 및 ASR 서버로 설정된 MRCPv1 세션의 연결을 해제합니다.
IOS 게이트웨이는 ISDN 측에서 통화를 연결 해제합니다.
