Dear All


It's really hard to understand the CUCM trace log, is there any document can help to understand it ?


I know there is a sofeware VLT, it can translate the SDI trace file to easy understand form,but I think this is not good engough , and this software will not translate all the log.

Hello,


I have created this document that describes how to track an H.323 call in a CUCM trace:


https://supportforums.cisco.com/docs/DOC-11779


I plan to create documents for SCCP and SIP at some point in the future, but this should get you started with the basics of H.323.


If you find it helpful, or have questions on the doc please feel free to rate or leave comments.

Not really, you only understand and learn how to read logs by experience or if you're lucky enough someone gives you some training on it.

VLT digests a lot of the messages and many times you'll miss the actual error.

The only real way to read a trace is just open it in a text editor.

Traces are really meant for TAC troubleshooting purposes, so that's why you won't find a doc titled "how to read and understand traces" in CCO.

What about using Triple Combo to help with reading the trace(s)?

If you have no experience reading traces it might help you, however just as VLT, you'll get the digested version so chances are the error message won't show up or you don't see where it fails.

The doc for H.323 call tracing was brilliant. When would you be creating docs for SCCP & SIP ? We've been waiting forever for it
