簡介

語音可擴展標籤語言(VXML)是由全球資訊網聯盟(W3C)定義的標準。 它旨在建立音訊對話，提供合成語音、口語識別、DTMF數字識別以及錄製的口語音訊。VXML伺服器和客戶端使用公認的HTTP協定交換VXML文檔/頁面。

Cisco Voice Portal(CVP)提供可通過電話訪問的智慧互動式語音響應(IVR)應用。CVP部署分為三種型別：

  1. 獨立服務

  2. CVP通話控制

  3. 呼叫隊列和轉接

合成語音和口語/DTMF數字功能由文本到語音轉換(TTS)和自動語音識別伺服器(ASR)提供。 IOS® VXML網關通過媒體資源控制協定(MRCP)與TTS/ASR伺服器通訊。 MRCP(RFC 4463)有兩個版本，即MRCPv1(MRCP over RTSP)和MRCPv2(MRCP over SIP)。

本文檔介紹使用MRCPv2 TTS/ASR伺服器的獨立服務部署中IOS語音XML網關到CVP呼叫的呼叫流程。在CVP VXML伺服器上部署了一個示例藥房應用程式。

呼叫流示例

本節介紹此配置示例產生的呼叫流。

  1. ISDN呼叫通過T1 PRI 3/0到達PSTN/VXML網關。

  2. IOS網關將POTS撥號對等體1匹配為此呼叫的入站撥號對等體。

  3. IOS網關將呼叫控制交給與撥號對等體1關聯的藥房服務。

  4. 與藥房服務關聯的CVP VXML/TCL指令碼向VXML伺服器傳送HTTP GET請求。

  5. VXML伺服器返回200 OK響應。此響應包含VXML文檔/頁面。

  6. IOS網關執行VXML文檔。

  7. 如果VXML文檔指定了音訊提示的URL，則IOS網關將下載音訊檔案並播放提示。

  8. 如果VXML文檔指定了音訊提示的文本，則IOS網關使用撥號對等體5與tts@172.18.110.76（TTS伺服器）建立SIP會話。建立SIP會話後，使用SIP INVITE的SDP 200 OK響應中提供的TCP埠號開啟與TTS伺服器的TCP連線。此TCP連線用於在IOS網關和TTS伺服器之間交換MRCP消息，例如SPEAK、SPEAK-COMPLETE。

    TTS伺服器將G.711ulaw RTP音訊流傳送到網關在SIP INVITE的SDP中提供的IP地址和UDP埠號。

  9. 如果VXML文檔指定網關以識別DTMF數字和/或口語，則IOS網關會使用撥號對等體6與asr@172.18.110.76（ASR伺服器）建立SIP會話。建立SIP會話後，它會使用SIP INVITE的200 OK響應的SDP中提供的TCP埠號開啟與ASR伺服器的TCP連線。此TCP連線用於在IOS網關和ASR伺服器之間交換MRCP消息，例如DEFINE GRAMMAR、COMPLETE、RECOGNITION和RECOGNITION-COMPLETE。

    IOS VXML網關將G.711ulaw RTP音訊流傳送到ASR在SIP 200 OK響應的SDP中提供的IP地址和UDP埠號。IOS VXML網關將PSTN使用者輸入的數字作為RTP-NTE事件傳送到ASR伺服器。

  10. 執行VXML文檔後，網關將傳送HTTP POST請求（包含一組引數），如VXML文檔/頁面的<submit>標籤中所指定。

  11. 對於伺服器傳送的每個VXML文檔，都會執行步驟6 - 10。

  12. 當VXML應用程式完成向呼叫方提供的服務時，它會傳送一個VXML文檔，該文檔在<form>元素中僅包含<exit/>標籤。

  13. IOS網關斷開與TTS和ASR伺服器建立的MRCPv2會話的連線。

  14. IOS網關會斷開ISDN端的呼叫。

Debug指令

配置IOS網關以在其日誌緩衝區中記錄調試並禁用「日誌控制檯」。

附註：使用 debug 指令之前，請先參閱有關 Debug 指令的重要資訊。

注意：以下命令用於配置網關，以便將調試儲存在網關的日誌緩衝區中：

  • service timestamps debug datetime msec

  • 服務序列

  • 無日誌控制檯

  • logging buffered 5000000 debug

  28. 網關向TTS伺服器傳送「SPEAK」 MRCP請求以播放「感謝呼叫」提示。

  29. TTS伺服器向SPEAK請求傳送「進行中」響應。

  30. TTS伺服器在發出「感謝呼叫」提示後傳送一則「SPEAK-COMPLETE」消息。

  31. 網關向TTS伺服器傳送「SPEAK」 MRCP請求以播放「選單」提示（輸入1或說Refil/輸入2或說pharmacist）。（未顯示調試輸出。）

  32. TTS伺服器傳送IN-PROGRESS， SPEAK-COMPLETE消息並完成提示播放。（未顯示調試輸出。）

  33. PSTN呼叫者輸入「1」以選擇重新填寫。網關將此數字作為RTP-NTE事件傳送到ASR伺服器。

  34. ASR伺服器向網關傳送「識別完成」消息，通知網關它識別到了所請求的一個事件（在本例中為數字1）。

  35. 在從ASR伺服器接收到成功的識別通知後，VXML網關傳送一個HTTP POST請求，如VXML文檔的SUBMIT標籤中所指定(3)。 此POST請求通知VXML伺服器PSTN呼叫方輸入了數字1。

  36. 然後VXML伺服器傳送另一個VXML文檔，要求呼叫者在此處輸入處方。（未顯示調試輸出。）

  37. 網關向TTS傳送MRCP消息以發出提示。（未顯示調試輸出，但它們類似於步驟28-30。）

  41. VXML伺服器傳送VXML頁面以收集取貨時間並通知呼叫方處方已準備好取貨。網關通過與TTS和ASR伺服器的互動執行這些頁面。（未顯示調試輸出。）

  42. VXML伺服器傳送的最終VXML文檔僅包含<form>中的<exit\>標籤。這將通知網關終止VXML會話。

  43. 網關終止VXML應用程式。

  44. 網關斷開與ASR伺服器建立的SIP會話的連線。

  45. 網關斷開與TTS伺服器建立的SIP會話的連線。

  46. 網關斷開ISDN端呼叫。
