AccountCode Column in CDR

Hello - I have added account code in each extension but the accountcode field is not populated in CDR. It used to work while back but not any more. Does any one know how to fix this problem? I am using FreePBX with Trixbox 2.4.2 and Asterisk 1.4.17-1.

I rebooted Trixbox and it appeared to fix the problem.
