Method for blocking facsimile transmissions to non-fax devices

摘要

Methods are disclosed for blocking fax transmissions to non-fax devices. When a fax call request is received from an originating fax device, it is determined whether the called party device is eligible to receive the fax transmission. If the called party device is not eligible to receive the fax transmission, the fax call request is blocked thereby causing the called party device not to receive the fax transmission and an error message may be sent to the originating fax device. If the called party device is eligible to receive the fax transmission, the fax call request is completed thereby enabling the called party device to receive the fax transmission.
