Server 2008 Fax Server console doesn't show outgoing faxes

We are sending faxes from Windows XP clients through our Server 2008 Fax Server. Most of the faxes are sent, however the Server Fax Console never shows any faxes as being sent. The Fax Console does show the Incoming faxes that have been received. What can I do to get a log of the outbound faxes so we know they were sent successfully?
Thanks.
