I am looking at the documents for an S8500 and there are a couple of parameters to set on the trunk group form to pass call charge data. Lets make sure you have those parameters set.

CDR Reports: y
Service Type: public-ntwrk
Supplementary Service Protocol: a
Charge Advice: end-on-request

You might have to busy the trunk group to make the Service Type change.

If you want to see for yourself what I am looking at start the Avaya document that you installed to your computer from the CD that came with the switch. Click on S8500 and choose Administration/Reference from there, then choose Administrator's Guide from there. Toward the bottom of that document you will see "Collecting Billing Information", under that you will see "Receiving Call-Charge Information". Open that menu item and you will see how to collect call charge info from ISDN and non-ISDN trunks.

This should solve your problem.
