How to get logs from CUCM for initiated calls

[Zaher Juha]

Dears,

like in Voice Gateway for initiated calls we can run debugs command like debug voip ccapi inout to know the calling and the called number and the status of the call, matched dial-peer, ... etc

Can we do the same in CUCM

Thanks in advance for your help

[Ayodeji Okanlawon]

Yes you can. You will need to enable cucm traces and use RTMT to download them You will also need to know how to read the traces..

Here is a link that tells you how to enable and collect traces

Thanks Ayodeji

The problem how to read it :)

is there any way just to know the status of the call like in ccapi codes

CDRs will give you a lot of information about calls. They won't give as much as the traces (such as patterns matched, etc) but, in my experience, usually suffice for 98% of troubleshooting.

Thanks Gordon,

What I need the status of the call like if i have an integration by sip with Avaya without CUBE only buetween CUCM and Avaya PABX just i want to know if the call manager forward the call or not

[Gordon Ross]

CDRs will tell you, amongst other things:

• Calling Number
• Called Number
• Answered Number (so when a call is diverted)
• Duration
• Device Names
• IP Addresses
• etc..

CDR is used mainly for call statistics, it is not designed for detailed troubleshooting. Reading cucm logs requires a detailed understanding of how different components function and some practice. It can be a little daunting.

This book is excellent. This is what I always recommend as the starting point..

Hi Ayodeji,

SIP understanding video on cisco community is awesome.

But I was trying to access your blog for sip trace understanding but getting authorization error even after logging into support portal with CCO

Is there any alternate path or location where I go and read this blog?

[Ayodeji Okanlawon]

Hi Deepshikha,

When I click on the link it works. Try it again. I don't have any alternate path for it.
