SYMPTOMS
If you configure the Fax service in Windows 2000 to answer calls manually, and if you use the same telephone line for fax and voice, you may experience the following problem. You pick up the phone to determine whether an incoming call is a voice call or a fax transmission. You click Yes in the Incoming Call dialog box, but you cannot answer the call to receive the fax.



CAUSE
This behavior occurs because the Fax service does not identify whether a call is a fax transmission based on fax tones from the sender of the fax. Online Help incorrectly states that you can click Yes to manually answer the call after you pick up the phone.



WORKAROUND
To work around this behavior, do one of the following:
 * Answer the call to determine whether it is a fax tone or a voice call. If it is a fax tone, hang up the phone, and then wait for the next call to accept the fax transmission. This is based on the assumption that the next incoming call that you receive is a redial attempt from the sender of the fax.
 * Use a separate phone line to send and receive faxes.
