IOS Voice XML Gateway to CVP Call Flow con MRCPv1 ASR / TTS

Introduzione

VXML (Voice Extensible Markup Language) è uno standard definito dal World Wide Web Consortium (W3C). VXML è progettato per creare dialoghi audio che forniscono sintesi vocale, riconoscimento delle parole pronunciate, riconoscimento delle cifre DTMF e registrazioni dell'audio parlato. Il server e i client VXML utilizzano il protocollo HTTP noto per lo scambio di documenti e pagine VXML.

Cisco Voice Portal (CVP) offre applicazioni IVR (Voice Response) intelligenti e interattive a cui è possibile accedere telefonicamente. Esistono tre tipi di distribuzione CVP:

• Servizio autonomo

• Controllo delle chiamate CVP

• Coda di chiamata e trasferimento

Sintesi vocale, riconoscimento vocale o funzioni DTMF vengono fornite dai server di sintesi vocale e di riconoscimento vocale automatico. Cisco IOS® VXML Gateway comunica con i server TTS e ASR utilizzando il protocollo MRCP (Media Resource Control Protocol). MRCP è disponibile in due versioni: MRCPv1 (MRCP over RTSP) e MRCPv2 (MRCP over SIP).

Questo documento descrive il flusso di chiamate da un gateway XML voce di Cisco IOS a una chiamata CVP in una distribuzione di servizi standalone che utilizza server MRCPv1 TTS o ASR. Un'applicazione farmaceutica di esempio è stata distribuita nel server VXML CVP.

Esempio di flusso di chiamata

In questa sezione viene descritto il flusso di chiamate risultante da questo esempio di configurazione.

1. Una chiamata ISDN arriva al gateway PSTN/VXML attraverso T1 PRI 3/0.

2. Il gateway IOS corrisponde al dial-peer POTS 1 come dial-peer in ingresso per questa chiamata.

3. Il gateway IOS consegna il controllo delle chiamate al servizio Pharmacy associato al dial-peer 1.

4. Lo script VXML/TCL CVP associato al servizio Pharmacy invia una richiesta HTTP GET al server VXML.

5. Il server VXML restituisce una risposta 200 OK. La risposta contiene un documento o una pagina VXML.

6. IOS Gateway esegue il documento VXML.

7. Se il documento VXML specifica un URL per un prompt audio, IOS Gateway scarica il file audio e riproduce il prompt.

8. Se il documento VXML specifica un testo per un prompt audio, IOS Gateway stabilisce una sessione RTSP con rtsp://10.86.177.39/synthesizer (server TTS). Una volta stabilita la sessione RTSP, il gateway e il server TTS scambiano messaggi MRCP quali TALK, TALK-COMPLETE utilizzando la richiesta RTSP ANNUNCE.

   Il server TTS invia il flusso audio RTP G.711ulaw all'indirizzo IP e al numero di porta UDP forniti dal gateway nell'intestazione "Transport" della richiesta di installazione RTSP.

9. Se nel documento VXML viene specificato il gateway in modo che riconosca le cifre e le parole DTMF, IOS Gateway stabilisce una sessione RTSP con rtsp://10.86.177.39/recognizer (server ASR). Una volta stabilita la sessione RTSP, il gateway e il server ASR si scambiano messaggi MRCP quali DEFINE GRAMMAR, COMPLETE, RECOGNITION, RECOGNITION-COMPLETE utilizzando la richiesta RTSP ANNUNCE.

   Il gateway VXML di IOS invia il flusso audio RTP G.711ulaw all'indirizzo IP e al numero di porta UDP forniti dall'ASR nel SDP della risposta RTSP 200 OK. IOS VXML Gateway invia le cifre immesse dall'utente PSTN come eventi RTP-NTE al server ASR.

10. Dopo l'esecuzione del documento VXML, il gateway invia una richiesta POST HTTP (con un set di parametri) come specificato nel tag <submit> del documento o della pagina VXML.

11. I passaggi da 6 a 10 si verificano per ogni documento VXML inviato dal server.

12. Quando l'applicazione VXML completa il servizio fornito al chiamante, invia un documento VXML con un semplice tag <exit/> all'interno dell'elemento <form>.

13. Il gateway IOS disconnette le sessioni MRCPv1 stabilite con i server TTS e ASR.

14. IOS Gateway disconnette la chiamata sul lato ISDN.
