注意：为原因i = 0x80 BA发出Cisco IOS debug命令debug isdn q931。这在“了解调试isdn q931断开原因代码”文档中解释。
注意：对于原因i = 0x82c1 — 未实现承载功能，网络无法提供用户请求的承载功能。这可能与Telco问题有关。
如果是这种情况，请在串行接口下添加命令。发出debug isdn q931并检查您是否仍遇到此问题。如果是，请发出debug isdn q931命令，并将这些Cisco IOS命令添加到配置中。
-
service timestamps debug datetime msec
-
service timestamps log datetime msec
再次进行测试呼叫，并检查debug isdn q931命令的输出。
在串行接口下添加isdn incoming-voice modem命令，以更改Cause i = 0x80BA的行为。

故障排除和验证
如果遇到任何问题，请结合Cisco IOS debug 命令debug isdn q931和Cisco PGW 2200消息定义语言(MDL)跟踪来收集SS7嗅探器跟踪。
收集Cisco PGW 2200 MDL跟踪
按照以下步骤收集MDL跟踪：
-
确定发出呼叫的始发SS7 SigPath Number或始发中继组Number。
-
运行/opt/CiscoMGC/bin/log_rotate.sh上的脚本，旋转日志。
-
通过发出sta-sc-trc:ss7sigPath名称启动MDL跟踪 | orig trunkgroup number命令并确认。如果需要更多详细信息，请通过人机语言(MML)发出help:sta-sc-trc help命令。
-
通过呼叫执行测试。
-
发出stp-sc-trc:all命令，停止MDL跟踪。
-
识别错误呼叫的呼叫ID(C:)。如果测试呼叫是在测试环境中进行的，则只显示一个呼叫ID。
以下是您在发出./get_trc.sh trace_file_name时收到的详细信息的示例:
/opt/CiscoMGC/bin mgcusr@PGW2200% ./get_trc.sh _ss7path_20040116104232.btr get_trc.sh ca/sim/sp Trace File Utility Mistral Version 1.2 The ANALYSIS mdo file is: GENERIC_ANALYSIS.mdo Retrieving _ss7path_20040116104232.btr trace file Call ID's, please wait... Enter one of the following commands: S = Simprint in less F = Simprint with printing of sent and received Fields in less D = Display trc trace in less G = Display trc trace in less (Generated) C = Convert to trc trace file A = Display CA file in less N = Move to Next call ID P = Move to Previous call ID L = List call ID's in current file X = Set SP flags H = Print Help Q = Quit get_trc.sh Or just enter the ID of the call you want if you know it Use (N)ext and (P)revious to move between the call ID's _ss7path_20040116104232.btr contains 10 call(s) ==> Working on call 1 ID 24 H = Help [S/F/D/G/C/A/N/P/L/H/Q/id]?注意：如果捕获是在生产Cisco PGW 2200上进行的，则这些文件可能包含许多混合呼叫跟踪。文件中的每个跟踪记录都具有特定的记录类型，并记录与该记录相关的类型的信息。每条记录都有一个呼叫ID，用于将其与特定呼叫关联。
-
将MDL跟踪转换为可读格式。转到目录/opt/CiscoMGC/bin并发出命令./get_trc.sh trace file name。
-
在提示符下键入Call ID，以跳至错误呼叫的MDL跟踪。
-
选择C选项以转换跟踪文件。
注：扩展名为.btr的文件是Cisco PGW 2200跟踪器功能生成的二进制跟踪文件。文件名的主要部分在Cisco PGW 2200 MML命令sta-sc-trc中给出。Cisco PGW 2200始终向这些文件添加.btr扩展名。使用“C”选项时，文件将转换为文本格式，扩展名.trc将添加到文件名中。这些文件包含来自生成文件的模拟重放中运行的MDO代码的逐行详细跟踪信息，因此它们包含MDL跟踪。
-
跟踪文件位于/opt/CiscoMGC/var/trace。将.btr和.trc文件上传到服务请求以供审核。
-
收集位于/opt/CiscoMGC/var/log的platform.log文件。
在某些情况下，在处理服务请求时，思科技术支持工程师要求报告与问题相关的其他platform.log信息。
收集监听/SIP-SS7嗅探器跟踪
本节列出了收集嗅探器踪迹的几种方法。您选择哪个选项取决于您是已安装Cisco Packet Telephony Center — 监控和故障排除(PTC-MT)，还是运行旧版本的Cisco监听程序。思科监听程序可以很好地了解SS7-SIP呼叫流。
-
在所有Solaris平台上发出snoop命令：
要收集UNIX监听信息，请以超级用户身份登录并发出命令：
snoop -o snoop.log IP address输入Ctrl+C退出snoop并将snoop.log文件上传到案例说明。
注意：在案例中说明此文件是使用UNIX snoop命令捕获的。
-
运行Cisco监听应用：
要收集Cisco监听信息，请以超级用户身份登录并发出./snooper int INTERFACE PARMS LIST命令或运行。/snooper，这将为您提供完整说明。
./snooper int hme'x' ni2+ ss7 > snooper_int1 !--- Where 'x' is the interface number, which you can also find !--- by issuing the ifconfig -a command.
注意：将snooper_int1文件上传到案例说明。
-
运行PTC-MT。
要收集PTC-MT信息，请以超级用户身份登录并发出./ptcmt int INTERFACE PARMS LIST命令或运行./snooper，这为您提供了完整说明。
./ptcmt int hme'x' ni2+ ss7 > snooper_int1 !--- Where 'x' is the interface number, which you can also find !--- by issuing the ifconfig -a command.
将“snooper_int1”文件上传到案例说明。
