In CM 5.x, the system was limited to 8MB of buffer, split across both primary and secondary CDR endpoints. That number is completely in memory and does not survive a system reset or forced interchange. I've heard that was increased in CM 6, but I don't think it was published for how large it actually is.
To give some context, we have a fairly busy system from 8am-8pm with about 20,000 endpoints. During the day, our system can buffer about 3-4 hours of CDR data with two endpoints before data is lost. At night and on the weekends, it lasts about 2-3 days.
The number of records is generally the number of calls. Depending on what you are storing, that could include external calls, internal calls, incoming and/or outgoing. That is highly dependent on your setup.

Hello Gustavo,
I think a lot of this answer is "it depends". There's a finite amount of space. Depending upon how many calls your system processes, it could last a very short time or a long time. Some CDR record formats are longer than others. Where are you drawing your numbers from? The capacity table?

Hi everyone, my questions is: 1- How long ( time ,secs, minutes, hours ) does the CDR buffer store if I only have a primary device ( link down )?
2- 17326 records corresponds to each device ( Primary / Second ) ?
3- what is 1900 records ?
4- each call corresponds to a record?
5- how is it interpreted in size ( KB, MB ) ?
My PBX is Main S8700 ( cluster ) version 6.3 , the CDR doesn´t store on local disk.
Thanks.
Regards,
