IOS PSTN入口网关到CVP (呼叫队列和收集)呼叫流的

简介

思科客户语音门户(CVP)提供可通过电话访问的智能交互式语音应答(IVR)应用。有三种CVP配置类型：

• 独立服务

• CVP呼叫控制

• 呼叫队列和收集

本文档从呼叫队列和收集部署中基于H.323的IOS®入口网关的角度描述呼叫流。

在呼叫队列和收集部署中，CVP与智能联系管理(ICM)交互，以制定呼叫路由决策。ICM请求CVP为来电提供语音响应单元(VRU)处理，以便播放菜单提示和收集数字以确定要选择的技能组。当技能组已确定且技能组中的座席可用时，ICM会请求CVP通过Cisco CallManager将来电连接到座席IP电话。如果座席不可用，ICM会请求CVP提供呼叫队列处理（例如，播放通话等待音乐提示）。CVP使用VXML网关提供VRU或呼叫队列处理。

呼叫流示例

本节介绍此配置示例产生的呼叫流：

1. ISDN呼叫通过T1 PRI 1/0/0到达PSTN/VXML网关。

2. IOS网关将POTS拨号对等体2作为此呼叫的入站拨号对等体。

3. IOS网关将VoIP拨号对等体1作为此呼叫的出站拨号对等体。

4. IOS网关将tech-prefix "2#"预置到被叫号码，并向网守发送ARQ。

5. 网守将呼叫路由到CVP。

6. CVP应答呼叫，并在IOS入口网关和CVP之间建立RTP媒体连接。

7. CVP将新呼叫通知ICM。

8. ICM运行与此呼叫的被叫号码关联的脚本。

9. ICM请求CVP提供VRU处理以播放菜单提示(Main_Welcome_Menu.wav)并收集数字以标识技能组。

   1. 1个TAC

   2. 销售2

   ICM还将网络VRU的ICM标签(8001112222)发送到CVP。

10. CVP向网守发送ARQ请求（目的地为网络VRU标签）。

11. 网守在ACF响应中提供VXML网关的IP地址。

12. CVP向VXML网关发送H225设置，然后VXML网关建立到CVP的VXML会话。请参阅以下URL了解VXML网关和CVP，以及VXML网关和ASR/TTS服务器交互：

    • MRCPv1

    • MRCPv2

13. CVP通过发送H245空TCS断开其现有RTP媒体连接到入口网关。

14. CVP在入口网关和VXML网关之间建立RTP媒体连接。

15. PSTN主叫方输入数字“1”以选择“TAC”技能组。入口网关通过RTP NTE将DTMF发送到VXML网关16)VXML网关通过VXML将数字报告给CVP，然后VXML向ICM报告。

16. VXML网关通过VXML将数字报告给CVP，然后VXML再报告给ICM。

17. 然后，ICM从所选技能组中找到一个可用的座席，并通过发送座席的ICM标签(3#75001)请求CVP将呼叫路由到座席。

18. CVP断开入口网关和VXML网关之间的现有RTP媒体连接。

19. CVP向网守发送ARQ请求（目的地=代理标签）。

20. 网守在ACF响应中提供Cisco CallManager的IP地址。

21. CVP将H225设置发送到Cisco CallManager，然后Cisco CallManager将呼叫建立到座席IP电话。

22. CVP在入口网关和代理电话之间建立RTP媒体连接。

23. PSTN主叫方在完成与座席的对话后挂断呼叫。

24. 入口网关断开与CVP的呼叫，并通知网守有关呼叫终止的信息。

25. 然后，CVP断开与CCM的呼叫。
