How to read CUCM trace log

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.

When are you creating the docs for SIP & SCCP ???

Hi,

Please refer to the blog below to learn how to read sip traces..

There is not much to SCCP. SCCP is what cucm uses to talk to IP Phones and vice versa.

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

Does downloading Voice Log Translator require a special entitlement or service contract association ?

Hi Anas,

As long as you have access to download software in cisco site, you can get VLT from cisco software download page.

https://software.cisco.com/download/home/284329957/type/282074326/os

But I would suggest that you use translatorX whcih is a better and useful tool compared to VLT which you can download online without any contract.
