Windows Fax Service not automatically answering incoming faxes

I have a Server 2003 Std that i installed the windows fax service on since our fax machine just died. It is configured to Automatically answer calls (faxes or not) after 1 ring. If a fax comes in, and i'm on the server, i can manually answer the fax and everything works fine. If i'm not, the call is never answered, and cannot figure out why. I am able to send faxes through this server just fine, and receive faxes manually, but not automatically.
I am using an Agere Systems PCI-SV92PP modem on Server 2003 Std. The fax line is an analog port with an extension on a digital phone system. We must manually send incoming faxes to the extension. Even when dialing the extension from the inside, the modem does not pick-up anticipating an incoming fax.
Is the problem the modem? Is it a port setting; if it is, why can i send and receive manually?
Thanks for all your help.

If you can communicate with modem via Hyperterm or other terminal client, and if this is standard modem, connect to it and say


then disconnect. After that modem should answer after first ring.

That got it somewhat working. I did a few test, and it looks like it's choosing when to answer. I tested dialing the extension from inside the phone system, and it answered automatically 2/10 times. I had someone send a test fax, and 1/6 tries was answered automatically. The others didnt answer at all. Any ideas?

Try to test that modem actually get the ring. Connect to it, temporary remove auto-answer with ATS0=0
and dial it's number from phone system. You should see the word "RING" _every_ time you dial. If not, something
is wrong with analog port or phone system.

Thanks for the testint tip medvedd. Did not see "Ring" when i dialed. Come to find out it was a bad modem. Put a new one in, and it works flawlessly. Thanks a bunch!
