The Tracker more than a modem, you can see it as a "mini" pc, It runs on a customized linux platform and can be attached to the network which can be internally firewalled by the tracker . To interpret alarms from a PBX, Datatrack developed phyton scripts for each brand (E///, Nortel, Siemens, Avaya). So, if you have mixed PBX enviromnent it can be very useful...
