IOS PSTN輸入閘道至CVP（通話佇列和收集）通話流程

簡介

思科客戶語音門戶(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：

• 獨立服務

• CVP通話控制

• 呼叫隊列和收集

本文檔從呼叫隊列和收集部署中基於H.323的IOS®入口網關的角度描述了呼叫流程。

在「呼叫隊列和收集」部署中，CVP與智慧聯絡人管理(ICM)互動以做出呼叫路由決策。ICM請求CVP提供語音響應單元(VRU)處理來電，播放選單提示，並收集數字以確定要選擇的技能組。在標識了技能組並且技能組中的座席可用時，ICM請求CVP通過Cisco CallManager將來話呼叫連線到座席IP電話。如果座席不可用，則ICM請求CVP提供呼叫隊列處理（例如，播放呼叫保持提示）。CVP使用VXML網關提供VRU或呼叫隊列處理。

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 1/0/0到達PSTN/VXML網關。

2. IOS網關將POTS撥號對等體2匹配為此呼叫的入站撥號對等體。

3. IOS網關將VoIP撥號對等體1匹配為此呼叫的出站撥號對等體。

4. IOS閘道將tech-prefix "2#"前加在被叫號碼上，並向Gatekeeper傳送ARQ。

5. 網守將呼叫路由到CVP。

6. CVP應答呼叫，並在IOS入口網關和CVP之間建立RTP媒體連線。

7. CVP通知ICM新呼叫。

8. ICM運行與此呼叫的被叫號碼關聯的指令碼。

9. ICM請求CVP提供VRU處理以播放選單提示(Main_Welcome_Menu.wav)並收集數字以標識技能組。

   1. 1個用於TAC

   2. 2個銷售部門

   ICM還將網路VRU的ICM標籤(8001112222)傳送給CVP。

10. CVP向網守傳送ARQ請求（目標=網路VRU標籤）。

11. 網守在ACF響應中提供VXML網關的IP地址。

12. CVP向VXML網關傳送H225設定，VXML網關隨後會向CVP建立VXML會話。請參閱以下URL以瞭解VXML網關和CVP以及VXML網關和ASR/TTS伺服器互動：

    • MRCPv1

    • MRCPv2

13. CVP通過傳送H245空TCS斷開其現有RTP媒體與入口網關的連線。

14. CVP在入口網關和VXML網關之間建立RTP媒體連線。

15. PSTN呼叫者輸入數字「1」以選擇「TAC」技能組。入口網關通過RTP NTE將DTMF傳送到VXML網關(16)VXML網關通過VXML將數字報告給CVP，然後報告給ICM。

16. VXML網關通過VXML向CVP報告數字，然後向ICM報告。

17. 然後，ICM從所選技能組查詢可用的座席，並請求CVP通過傳送座席的ICM標籤(3#75001)將呼叫路由到座席。

18. CVP斷開入口網關和VXML網關之間的現有RTP媒體連線。

19. CVP向網守傳送ARQ請求（目標=代理標籤）。

20. 網守在ACF響應中提供Cisco CallManager的IP地址。

21. CVP向Cisco CallManager傳送H225設定，然後Cisco CallManager會建立對座席IP電話的呼叫。

22. CVP在入口網關和代理電話之間建立RTP媒體連線。

23. PSTN呼叫者在結束與座席的對話後掛斷呼叫。

24. 入口網關斷開與CVP的呼叫，並向網守通知呼叫終止。

25. 然後CVP斷開與CCM的呼叫。
