asterisk users - Feb 2005 - CDR for callback

Some of my clients of hosted PBX service want to use it for callback
when they cannot use the ATA.

This is the scenario

1. Asterisk calls Party A at numA.
2. When A picks up the phone, he hears the announcement to enter the
destination number, numB. He enters numB
3. Asterisk Dials numB and party A and B talk.

This works well. However, there is no CDR generated.

Is there a way I can force the CDR generation?

If it helps, both the legs are on OH323 channels.

Thanks,
