Introduction

Voice Extensible Markup Language (VXML) is a standard defined by the World Wide Web Consortium (W3C). VXML is designed to create audio dialogs that provide synthesized speech, recognition of spoken words, recognition of DTMF digits and recordings of spoken audio. The VXML server and clients use the well-known HTTP protocol to exchange VXML documents and pages.

Cisco Voice Portal (CVP) delivers intelligent and interactive voice response (IVR) applications that can be accessed over the phone. There are three types of CVP deployments:

  • Standalone Service

  • CVP Call Control

  • Call Queue and Transfer

Synthesized speech, recognition of spoken words or DTMF digit functionalities are provided by Text-to-Speech (TTS) and Automatic Speech Recognition (ASR) servers. Cisco IOS® VXML Gateway communicates with the TTS and ASR servers using Media Resource Control protocol (MRCP). There are two versions of MRCP (RFC 4463), namely MRCPv1 (MRCP over RTSP) and MRCPv2 (MRCP over SIP).

This document describes the call flow of a Cisco IOS Voice XML Gateway to CVP call in a Standalone Service deployment that uses MRCPv1 TTS or ASR servers. A sample pharmacy application was deployed at the CVP VXML server.

Call Flow Example

This section describes the call flow that results from this configuration example.

  1. An ISDN call arrives at the PSTN / VXML Gatway across T1 PRI 3/0.

  2. IOS Gateway matches POTS dial-peer 1 as the inbound dial-peer for this call.

  3. IOS Gateway hands off the call control to the Pharmacy service that is associated to dial-peer 1.

  4. The CVP VXML / TCL script associated with the Pharmacy service sends an HTTP GET request to the VXML server.

  5. The VXML server returns a 200 OK response. This response contains a VXML document or page.

  6. IOS Gateway executes the VXML document.

  7. If the VXML document specifies a URL for an audio prompt, IOS Gateway downloads the audio file and plays the prompt.

  8. If the VXML document specifies a Text for an audio prompt, IOS Gateway establishes a RTSP session with rtsp://10.86.177.39/synthesizer (TTS Server). After the RTSP session is established, the Gateway and TTS Server exchange MRCP messages such as SPEAK, SPEAK-COMPLETE by using the RTSP ANNOUNCE request.

    The TTS Server sends the G.711ulaw RTP audio stream to the IP address and UDP port number provided by the Gateway in the “Transport” Header of the RTSP SETUP request.

  9. If the VXML document specifes the Gateway to recognize DTMF digits and spoken words, IOS Gateway establishes a RTSP session with rtsp://10.86.177.39/recognizer (ASR server). After the RTSP session is established, the Gateway and ASR server exchange MRCP messages such as DEFINE GRAMMAR, COMPLETE, RECOGNIZE, RECOGNITION-COMPLETE by using the RTSP ANNOUNCE request.

    The IOS VXML Gateway sends the G.711ulaw RTP audio stream to the IP address and UDP port number provided by the ASR in the SDP of the RTSP 200 OK response. The IOS VXML Gateway sends the digits entered by the PSTN user as RTP-NTE events to the ASR server.

  10. After the execution of the VXML document, the Gateway sends an HTTP POST request (with a set of parameters) as specified in the <submit> tag of the VXML document or page.

  11. Steps 6 – 10 occur for each VXML document sent by the server.

  12. When the VXML Application finishes the service provided to the caller, it sends a VXML document with just a <exit/> tag within the <form> element.

  13. IOS Gateway disconnects the MRCPv1 sessions established with the TTS and ASR servers.

  14. IOS Gateway disconnects the call on the ISDN side.
