AWFAX Using Sportster Modem Fails Group 3 Fax Connection

SYMPTOMS

When you use a U.S. Robotics 14,400 Sportster modem with Microsoft At Work Fax to send a fax to a Group 3 fax machine, the modem may either successfully dial out but fail to make a connection or successfully negotiate the connection but fail to transmit the fax. A successful connection but failed fax transmission will cause the fax message to appear in the sender's Inbox marked as undeliverable mail.
