I have cdr data exported from a database,
in the userfield column it has one of
IN, OUT, EXTFW - 140 and ININ;IN
I assume this is something to do with the direction of a call
Unfortunatly it seems that CDR is not consistant across versions of the Asterisk.
Have you made any progress decoding the data as I have the same problem.
The information at http://www.voip-info.org/wiki/view/Asterisk+billing
is sadly lacking.[/url], any further information on the cdr fields would be appreciated.
