soo, I was in the basement a couple months ago, and I saw our schools telephone system. I found the model of it, wich was a mitel SX200 lite. Pretty common phone system to use in schools. Since then me and a few friends have been general idiot teenagers, and doing various lame things. things to do for instant hillarity: walk up to random teachers phone, flash the handset and punch in 22 + extension of student phone. All calls to that teacher will now forward to student phone get a friend to take a phone off the hook and make sure it stays that way. Walk around school (having multiple people working on this helps) and go to every phone you see and dial the extension of the phone you took off the hook. When you get a busy tone, hit 1 and hang up. Wait until class starts and then hang up the phone you had off the hook. Now every phone you and your buddies used to call the busy phone will ring at the same time. Pretty entertaining during class time. call up a sex hotline from the public phone. Hit flash and then the extension of a random teacher to transfer the call to them. you can also forward calls from one teacher to another. That will confuse the hell out of the office once you do this to a bunch of rooms. Even better, at lunch go out and forward calls from 20 other rooms to whatever class you have in the afternoon. That should piss off you teacher. okay, okay. You all think i'm a loser now. I still think i'm funny. I love highschool QUESTION TIME! One time I saw a teacher walk up to his phone, hit an extension and get the PA system. Any way to find out what extension it could be? phone features, if you're curious. hold = flash + 44 un-hold = flash + 45 transfer = hold, flash + extension number confrence call = flash + phone number or extension, then flash + 38 to get back in the conversation monitor (phone will ring when line or extension is no longer in use) = @ busy signal, hit 1 then hang up urgent call = at busy signal, hit 3 forward all calls = 22 + extension thats all I know of. If anyone has anything to add i'd appreciate it. now, one more thing. I've seen a teacher punch in an extension and then page over the PA system. Now... lets say someone... forwarded a call to the PA. Like, a call from a phone sex hotline. 1) how could someone disconnect the call? 2) how would I find the extension to the PA?
