CDR missing information - Outbound trunk

[daktur]

Hi All,

I am setting up an invoice system based on CDR information to bill my customers.
I have checked to log all possible information on the CDR for each call and only 1 file for all calls.

A super important information I need to know in order to bill them is the trunk used to place the outbound call but i cannot find this information nowhere in the file.

Can you please hint me what is the field name for this information? Is it possible that this information is not recorded?

I am runningV14 SP3 on a windows server with 12 extensions and 2 trunks

For everyone's information as on https://www.3cx.com/docs/cdr-call-data-records/ unfortunately the file does not contain this information.
