目录
简介
Cisco Unified Mobile Agent使使用任何公共交换电话网(PSTN)电话和宽带VPN连接（用于座席桌面通信）的座席能够像使用由Cisco Unified Communications Manager(CUCM)Java电话应用编程接口(JTAPI)监控和控制的Cisco IP电话的正式呼叫中心中的座席一样工作。 Cisco Unified Mobile Agent允许系统管理员将代理配置为使用按呼叫拨号或固定连接。在逐个呼叫模式下，移动座席的电话会针对每个来电拨号。当呼叫结束时，移动座席的电话在准备好接听下一次呼叫之前会断开。本文档跟踪JTAPI网关(JGW)和CUCM日志中对逐个呼叫移动座席的入站呼叫。这包括两个呼叫段，一个从客户到本地CTI端口(LCP)，另一个从远程CTI端口(RCP)到座席。目标是捕获JGW如何让CUCM桥接两个呼叫段。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档中的信息基于以下软件和硬件版本：
- 统一联络中心企业版10.0版
- CUCM版本10.0
概述
呼叫详细信息
座席电话和客户电话都是通过ISDN PRI连接到CUCM连接网关的Communications Manager Express(CME)的分机。
CME---- ISDN PRI--- SIP Gateway (10.106.61.162)--- CUCM (10.106.81.67)
LCP : LCP5000F0001, DN 6001
RCP : RCP5000F0001, DN 6101
Agent mobile number : 2003
Caller number: 2001
PG IP Address: 10.106.81.68
CVP IP Address:10.106.81.69
高级呼叫流
- CME上的呼叫方2001拨打9001，指向网关(GW)(10.106.61.162)。GW拨号对等点指向客户语音门户(CVP)。
- CVP向智能联系管理器(ICM)发送路由请求，ICM返回移动代理标签，即LCP端口拨号号码(DN)6001。
- CVP向CUCM发送邀请。当LCP端口振铃时，JTAPI网关(JGW)指示CUCM从RCP 6101呼叫代理电话2001。
- 座席应答后，座席腿将连接到通话等待音乐(MoH)。
- JGW指示CUCM应答在LCP端口上振铃的入站呼叫。
- 一旦LCP支路连接，JGW将指示CUCM检索代理支路。
- JGW将实时传输协议(RTP)IP地址/端口详细信息从客户支路传递到座席支路，反之亦然。
- CUCM桥接两条腿，并在座席和客户之间建立RTP路径。
此分析从第3步开始，当呼叫到达CUCM LCP端口时。每个JGW代码段后跟分别由报头JGW和CUCM标识的CUCM日志代码段。
故障排除
使用以下调试级别对CUCM上对应的JGW消息和会话初始协议(SIP)信令进行故障排除：
JTAPI
在座席外围网关(PG)上，使用Procmon实用程序启动JGW进程的跟踪：
C:\>procmon <cust_inst> <node> jgw<jtapi instance>
>>>trace JT_TPREQUESTS /on
>>>trace JT_JTAPI_EVENT_USED* /on
>>>trace JT_PIM_EVENT /on
>>>trace JT_ROUTE_MESSAGE /on
>>>trace *CONF* /on
注意：trace命令区分大小写。
