Billing Interface

Three new fields have been added to the Call Data Blocks (CDBs) to support the T.38 fax relay feature:

transmissions. This indicator can have one of the following values:

–

Not Fax = 1

Not Fax (1) indicates that no fax transmissions occurred, the other two values (2 or 3) indicate that

faxes were sent or received. If faxes were sent, the number of pages is indicated by the next field.

If faxes were received, the number of pages is indicated by the third field.
