简介

语音可扩展标记语言(VXML)是万维网联盟(W3C)定义的标准。VXML旨在创建音频对话，提供合成语音、口语词的识别、DTMF数字的识别和口语音频的录音。VXML服务器和客户端使用公认的HTTP协议来交换VXML文档和页面。

思科语音门户(CVP)提供可通过电话访问的智能交互式语音应答(IVR)应用。有三种CVP配置类型：

  • 独立服务

  • CVP呼叫控制

  • 呼叫队列和转接

合成语音、口语识别或DTMF数字功能由文本到语音(TTS)和自动语音识别(ASR)服务器提供。Cisco IOS® VXML网关使用媒体资源控制协议(MRCP)与TTS和ASR服务器通信。 MRCP(RFC 4463)有两个版本，即MRCPv1(MRCP over RTSP)和MRCPv2(MRCP over SIP)。

本文档介绍在使用MRCPv1 TTS或ASR服务器的独立服务部署中Cisco IOS语音XML网关到CVP呼叫的呼叫流。在CVP VXML服务器上部署了一个药房应用示例。

呼叫流示例

此部分描述该的呼叫流从此配置示例的结果。

  1. ISDN呼叫通过T1 PRI 3/0到达PSTN/VXML网关。

  2. IOS网关将POTS拨号对等体1作为此呼叫的入站拨号对等体。

  3. IOS网关将呼叫控制移交给与拨号对等体1关联的药房服务。

  4. 与药房服务关联的CVP VXML/TCL脚本向VXML服务器发送HTTP GET请求。

  5. VXML服务器返回200 OK响应。此响应包含VXML文档或页面。

  6. IOS网关执行VXML文档。

  7. 如果VXML文档为音频提示指定URL，IOS网关将下载音频文件并播放提示。

  8. 如果VXML文档为音频提示指定了文本，IOS网关将与rtsp://10.86.177.39/synthesizer（TTS服务器）建立RTSP会话。 建立RTSP会话后，网关和TTS服务器使用RTSP ANNOUNCE请求交换MRCP消息，例如SPEAK、SPEAK-COMPLETE。

    TTS服务器将G.711ulaw RTP音频流发送到RTSP设置请求的“传输”报头中网关提供的IP地址和UDP端口号。

  9. 如果VXML文档指定网关识别DTMF数字和口语，IOS网关将与rtsp://10.86.177.39/recognizer（ASR服务器）建立RTSP会话。 建立RTSP会话后，网关和ASR服务器使用RTSP ANNOUNCE请求交换MRCP消息，如DEFINE GRAMMAR、COMPLETE、RECOGNITE、RECOGNITION-COMPLETE。

    IOS VXML网关将G.711ulaw RTP音频流发送到RTSP 200 OK响应的SDP中ASR提供的IP地址和UDP端口号。IOS VXML网关将PSTN用户输入的数字作为RTP-NTE事件发送到ASR服务器。

  10. 执行VXML文档后，网关发送HTTP POST请求（包含一组参数），如VXML文档或页面的<submit>标记中所指定。

  11. 步骤6 - 10针对服务器发送的每个VXML文档。

  12. 当VXML应用程序完成向调用方提供的服务时，它会发送一个VXML文档，该文档在<form>元素中仅包含<exit/>标记。

  13. IOS网关断开与TTS和ASR服务器建立的MRCPv1会话。

  14. IOS网关断开ISDN端的呼叫。
