First, make sure you do not have a phone off the hook - check for dial tone on any phone on the same phone line. Second, make sure alarm system power light is on, and that any battery backup is not dead, and that the system has not been turned off if the autocheck requires it be on.
Then, you might let the security company know you are doing testing so they don't call you if they detect what you are doing. First, I would check your phone line from the security system to the phone box outside - someone might have disconnected it to burgle the house, and either you did not realize you had been burgled or they changed their mind or got scared off, or the connection just went bad. If looks OK (I wold unplug and plug back in, to be sure connection is good) then take another phone that you know works OK and plug the cord jack that plugs into the security system panel into the phone instead and make a call to weather report or time and temp or whoever. If that works OK then phone line is OK. If not, go to the outside jack where the alarm system phone line plugs in to the phone compnay connection box and see if you can make a call. If so, then the wire between there and the alarm box or one of the two wire connectors is bad, which can be repaired by an alarm/security company or the telephone company (not free by phone company, unless you have their inside wiring maintenance contract). Those two tests tell you the phone line is good or not. If not a bad wire, then call the security company to arrange a test alarm, and with all phones on their cradles then trigger the alarm system to see if they detect it. If so, then see if they can initiate an autotest. If it fails, then the alarm box and not the line is bad. If it works, thenn you had a dirty or bad phone wire connection. Otherwise, if autocheck does not work still, could be the dialer or the alarm circuit board. You then need an alarm specialist - your security company if they installed it, else whoever installed it, or a local security system installation company with good ratings and reviews.
