Cisco CUCM – CDR through SQL

Hey everybody,

Today’s post is going to be quick, but may give you some good tips Smile
Last week I got some requests from a Customer, and he needed to know which extensions were recently being used . In order to save licenses, he wanted to delete all phones/lines that weren’t being used.

CDRs on CUCM is a nightmare in my opinion. Mainly when you need to check lots of lines, for a long period.
That’s why I decide to pull this information out directly from SQL.

So here are some useful commands to get CDRs from SQL, and depending on your needs and knowledge, you can use Python or other language to built your own CDR Reporting Smile

First of all, to use the commands you need to ensure that the following steps are taken on your CUCM system:

  1. Activate the CDR Analysis and Reporting (CAR) service on the CUCM publisher node.
  2. Go to System > Service Parameters and set the Cisco Call Manager service “Call Diagnostics Enabled” parameter to true on every cluster node that has the Call Manager service activated.

Now, going to SQL, this is the structure of any SQL Command on CUCM:
admin: run sql select [field list] from [table] where [expression]

The table we are going to use is tbl_billing_data. This table stores all of the elements we need to accomplish the task at hand.

So this is going to be our syntax: run sql select + column + from tbl_billing_data + where + column + (like,in,between,etc).

PS: Please not this command is only acceptable on Publisher.

In my example, I want to get Date (TimeStamp) , Calling and Called Number of all calls from extensions which have “702709” in their numbers and happened this month.

The date must be sent in TimeStamp mode. I use THIS SITE to convert normal date to Timestamp, and vice versa. If you were pulling CDR data into Excel then you can use the following formula (in a new cell) to do the conversion:

Right, so this is the command:

run sql car select datetimeOrigination,callingPartyNumber,finalCalledPartyNumber from tbl_billing_data where callingpartynumber like ‘%702709%’ and datetimeconnect > ‘1630486076’

And here is the result:

Well, now you can explore and play a bit more, depending on your needs. You can add more columns, like duration, destIpAddr, callingPartyNumber_uri, originalCalledPartyPattern,callingPartyNumberPartition,EU_SIP_SME_NOS….

That’s it guys. As I said, it was really quick Smile

Hope you’ve enjoyed!
