It's just a personal opinion but I think the OSN phone is pretty worthless. Get yourself a small programmable buffer box, like omnitronix and hook it up to a maint serial port on the system. Program it to keyword check its incoming data stream and when the letters OSN show up, capture the next several lines, and spit them out as an email or text message to those people who need to see it. That way you have a record of time, date, who, where, etc. That's how I alert the security staff, when someone dials 911 either on purpose or mis-dial. When the local PSAP calls security to verify a hangup, security already has an answer as to who dialed; even if they aren't in the office when it happened. I think there are other 911 screenpop solutions out there also, my VxTracker call accounting software can do 911 dial alerts almost instantly also...
