Product Description: The Stick® Call Processor automatically screens and routes all voice, fax and modem calls to the right equipment every time, eliminating the need for a rarely used dedicated phone line. It is even compatible with virtually all multi-line KSU and PBX phone systems. When installed on the last incoming line before a PBX or KSU, The Stick will route fax and modem calls directly to those devices and voice calls through the phone system.
