The Voice Debug Lookup tool provides the most useful debug and show
commands used to resolve a given type of voice-related problem. There
are many different and distinct categories for a voice problem in a
network. This tool clearly identifies the most helpful debug and show
commands toward a resolution given the protocols, features, platform,
and functionality used in your voice network. The user identifies the
protocols, features, platform, and functionality, with the provision
that the problem experienced is directly or indirectly related to these
aspects of the network. The tool then lists the most helpful debug and show commands which are collected from the network.
The information provided by this tool enables the Cisco Technical
Support engineer to resolve your problem faster and more efficiently
when you open a Technical Support service request. It also familiarizes
you further with the problem and the associated debug and show commands to identify the source of the problem. The tool does not explain how to interpret the debug and show command output.
In order to benefit from the Voice Debug Lookup tool, you need
access to your network and the ability to turn on debugs and capture

Complete these steps in order to best utilize the Voice Debug Lookup tool for your Technical Support service request:
- Identify the type of problem in your voice network.
- Find the set of appropriate debug and show commands using the Voice Debug Lookup tool.
- For Cisco IOS Gateways and Cisco CallManager Express, configure the
router to log the debugs in the router logging buffer or syslog server.
This step is necessary because the voice debugs are intensive in size.
For further details, choose either the How to collect debugs in IOS Voice Gateway or How to collect debugs in CCME option in the Voice Debug Lookup tool.
Refer to these documents for Cisco 6608 Gateway and Cisco CallManager trace configuration information:
- Enable the debugs in the origination and destination gateways/devices.
- Recreate the problem.
- Collect the debug and show command output from the router logging buffer or syslog server.
Open a service request and attach the collected debug and show
command output to the service request notes. You also can send this
information directly to the Technical Support engineer if you have
already opened a service request.
