An analog-device port on the Sportster allows you to originate and receive phone calls and faxes over your ISDN line. In addition, the Sportster supports dynamic bandwidth allocation, which allows you to receive data over the Internet while talking on the phone or sending a fax. However, incoming calls won't cause your phone to ring; the speaker mounted on the Sportster rings instead. To the Sportster's credit, its ISDN diagnostics are still some of the best out there. You can access information about the status of a call from start to finish or, for the really ISDN savvy, debug problems on the line by looking at ISDN events on each network layer.
