Nota tecnica sul flusso di messaggi VB 11.6 con flusso di chiamate completo

Introduzione

Questo documento descrive il flusso di messaggi su Cisco Virtualized Voice Browser (VB) con un flusso di chiamate completo. 

Prerequisiti

 Nessun requisito specifico previsto per questo documento.

Componenti usati

• VB versione 11.6
• Cisco Unified Customer Voice Portal (CVP) versione 11.6

 Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi

Informazioni generali

Flusso di chiamata:

Gateway in ingresso > CVP > Intelligent Contact Management (ICM) > Restituisci etichetta VRU > CVP > VB

Come mostrato nell'immagine, si tratta di un flusso di chiamate completo.

 Come mostrato nell'immagine, questo documento si concentra maggiormente sulla parte dei messaggi VB.

Messaggi VB

Passaggio 1. VB riceve SIP INVITE da CVP e finisce i messaggi SIP di Exchange.

256317: Oct 23 10:10:36.668 AEST %MIVR-JASMIN-7-UNK:[CALLID=B42C468000010000000000650851430A-150871535521622] NEW_CALL, GUCID=B42C468000010000000000650851430A; GUID=3022800512-0000065536-0000000101-0139543306; CallId=B42C468000010000000000650851430A-150871535521622@10.66.75.49; URI=sip:888811111139@10.66.75.62;transport=tls

256334: Oct 23 10:10:36.719 AEST %MIVR-JASMIN-7-UNK:[CALLID=B42C468000010000000000650851430A-150871535521622] SIP-ltp92-88881111*, State=ALERTED: Sending 200 OK response.

256335: Oct 23 10:10:36.785 AEST %MIVR-JASMIN-7-UNK:[CALLID=B42C468000010000000000650851430A-150871535521622] SIP-ltp92-88881111*, State=ALERTED: Processing ACK

 

Passaggio 2. VB recupera il file bootstrap.vxml localmente.

256398: Oct 23 10:10:36.794 AEST %MIVR-SS_VB-7-UNK:[CALLID=B42C468000010000000000650851430A-150871535521622] Fetch:    file:/opt/cisco/uccx/Documents/System/bootstrap.vxml


256401: Oct 23 10:10:36.795 AEST %MIVR-SS_VB-7-UNK:[CALLID=B42C468000010000000000650851430A-150871535521622] Successfully fetched bytes: 0, duration(s): 0.001, URI: file:/opt/cisco/uccx/Documents/System/bootstrap.vxml

 Passaggio 3. VVB invia CALL_NEW al CVP.

Quindi il CVP invia all'ICM: REQUEST_INSTRUCTION, ICM passa quindi le informazioni dell'applicazione a CVP.

256469: Oct 23 10:10:36.809 AEST %MIVR-SS_VB-7-UNK:[CALLID=B42C468000010000000000650851430A-150871535521622] Browser.makeRequest(): got encoded uri=http://10.66.75.49:7000/CVP/Server?MSG_TYPE=CALL_NEW&CALL_DNIS=888811111139&CALL_ANI=sip%3A60006099%4010.66.75.49%3A5061%3Btransport%3Dtls&ERROR_CODE=0&RECOVERY_VXML=crtp%3A%2FSDocuments%2FRecovery.vxml&CLIENT_TYPE=IOS&CALL_ID=B42C468000010000000000650851430A&CALL_LEGID=B42C468000010000000000650851430A-150871535521622%4010.66.75.49&CALL_UUI=&VERSION=Voice_Browser_11_6&PRIMARY=10.66.75.49
