Hi Community,
Is there a documentation regarding the Call Detail Logs in any of the OSMO Elements such as Call Information (call started, duration and end/caller and callee information,etc...) and SMS Information (sent/received time/sender and receiver,etc...)?
And may we know what log level configuration do we need to configure for us to see those information?
Thanks in advance.
Best Regard,
Ron Menez ron.menez@entropysolution.commailto:ron.menez@entropysolution.com

The component that knows most about caller identities and duration is the MSC, but it doesn't (yet) conveniently summarize call details anywhere. More suited would be the use of an external call router via MNCC, I guess.

Thanks for info Neels.

Hello Ron, It's been a few months since I've worked with the osmocom CDR's, but from memory I think what you're looking for is the cdr configuration option. In osmocom, "log" refers to the logs of the actual programs (think what you would see in syslog). I've only ever used cdr's in the SGSN to track data usage for billing, but I believe you can get the same information on the circuit switched side of the world too. In the SGSN, the relevant config line is detailed in the latest SGSN manual http://ftp.osmocom.org/docs/latest/osmosgsn-usermanual.pdf , although suspiciously the cdr config options are not listed under the SGSN vty reference anymore. Regards, -Matt J.

Thanks for the input Matthew.
We’ll explore the CDR from other OSMO elements if it is still available.

Hi Matthew,
thanks for sharing your experience!

Unfortunately we don't have any CDR generation in OsmoMSC. This reasons are twofold:
a) this is an "enterprise" feature, i.e. nothing that you'd need for research/lab type use, and hence nothing that anyone would likely volunteer to do in their spare time. The SGSN CDR was developed under funding from a specific enterprise user who had a related requirement.
b) most networks don't end at the MSC but they actually have some kind of other (soft)switch infrastructure behind the MSC, and hence the voice call related logs can be obtained there. This doesn't apply to the same degree for SMS, though.
although suspiciously the cdr config options are not listed under the SGSN vty reference anymore.
This is definitely not how it's supposed to be. Would you mind opening a new issue about this in the OsmoSGSN issue tracker at https://osmocom.org/projects/osmosgsn/issues ? Thanks!
Hello Harald, I went to go file the bug, and realized that I had made an error! I was looking quickly through several manuals at the same time, and was searching the GGSN VTY reference by accident.
Ron, The details on the CDR configuration options for the SGSN are available as expected in the SGSN's VTY reference manual http://ftp.osmocom.org/docs/latest/osmosgsn-vty-reference.pdf
Cheers, -Matt J.
