Flusso di chiamata da Gateway in entrata PSTN a CVP (coda di chiamata e raccolta) IOS
Sommario
Introduzione
Cisco Customer Voice Portal (CVP) fornisce 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 chiamate e raccolta
Questo documento descrive il flusso di chiamate dalla prospettiva di IOS® Ingress Gateway basato su H.323 in una coda di chiamate e nell'implementazione di Collect.
Nella distribuzione Call Queue and Collect, il CVP interagisce con Intelligent Contact Management (ICM) per prendere decisioni relative al routing delle chiamate. ICM richiede al CVP di fornire il trattamento VRU (Voice Response Unit) alla chiamata in arrivo per le richieste di menu di riproduzione e la raccolta di cifre per determinare il gruppo di abilità da selezionare. Una volta identificato il gruppo di abilità e disponibile un agente del gruppo di abilità, ICM richiede al CVP di connettere la chiamata in arrivo all'Agent IP Phone tramite Cisco CallManager. Se l'agente non è disponibile, ICM richiede a CVP di fornire il trattamento della coda di chiamate (ad esempio riprodurre un prompt di musica in attesa). CVP fornisce il trattamento della VRU o della coda di chiamate utilizzando un gateway VXML.

Esempio di flusso di chiamata
In questa sezione viene descritto il flusso di chiamate risultante da questo esempio di configurazione:
-
Una chiamata ISDN arriva al gateway PSTN/VXML tramite T1 PRI 1/0/0.
-
Il gateway IOS corrisponde al dial-peer 2 POTS come dial-peer in ingresso per questa chiamata.
-
Il gateway IOS corrisponde al dial-peer VoIP 1 come dial-peer in uscita per questa chiamata.
-
IOS Gateway antepone il prefisso tecnico "2#" al numero chiamato e invia un messaggio ARQ a Gatekeeper.
-
Gatekeeper instrada la chiamata a CVP.
-
Il CVP risponde alla chiamata e la connessione multimediale RTP viene stabilita tra IOS Ingress Gateway e CVP.
-
Il CVP informa ICM della nuova chiamata.
-
ICM esegue lo script associato al numero chiamato della chiamata.
-
ICM richiede al CVP di fornire un trattamento VRU per riprodurre un prompt Menu (Main_Welcome_Menu.wav) e di raccogliere cifre per identificare il gruppo di abilità.
-
1 per TAC
-
2 per Sales
L'ICM invia anche l'etichetta ICM (800111222) della VRU di rete al CVP.
-
-
Il CVP invia una richiesta ARQ (con destinazione = etichetta Network VRU) al Gatekeeper.
-
Gatekeeper fornisce l'indirizzo IP del gateway VXML nella risposta ACF.
-
CVP invia un'installazione H225 a VXML Gateway per stabilire una sessione VXML a CVP. Per informazioni sulle interazioni tra VXML Gateway e CVP e tra VXML Gateway e server ASR/TTS, fare riferimento agli URL seguenti:
-
CVP disconnette la sua connessione multimediale RTP esistente al gateway in ingresso inviando H245 Empty TCS.
-
Il protocollo CVP stabilisce una connessione multimediale RTP tra il gateway in ingresso e il gateway VXML.
-
Il chiamante PSTN immette la cifra "1" per selezionare il gruppo di abilità "TAC". Il gateway in ingresso invia il DTMF tramite RTP NTE a VXML Gateway (16) VXML Gateway segnala le cifre a CVP tramite VXML, che a sua volta fa riferimento a ICM.
-
VXML Gateway comunica le cifre a CVP tramite VXML, che quindi segnala a ICM.
-
ICM trova quindi un agente disponibile dal gruppo di abilità selezionato e richiede al CVP di instradare la chiamata all'agente inviando l'etichetta ICM (3#75001) dell'agente.
-
CVP disconnette la connessione multimediale RTP esistente tra il gateway in ingresso e il gateway VXML.
-
Il CVP invia una richiesta ARQ (con destinazione = etichetta dell'agente) al Gatekeeper.
-
Gatekeeper fornisce l'indirizzo IP di Cisco CallManager nella risposta ACF.
-
CVP invia una configurazione H225 a Cisco CallManager, che stabilisce una chiamata all'Agent IP Phone.
-
CVP stabilisce una connessione multimediale RTP tra il gateway in ingresso e il telefono dell'agente.
-
Il chiamante PSTN interrompe la chiamata dopo aver terminato la conversazione con l'agente.
-
Il gateway in ingresso disconnette la chiamata al CVP e informa il Gatekeeper della terminazione della chiamata.
-
CVP disconnette quindi la chiamata a CCM.
