If you can receive but not send, maybe the number you are sending to should include some pauses, especially at the end of the number. If you have a good dial-tone when you do "On-Hook" then there is nothing preventing you from sending on the machine end. Has the phone system just gone digital? You may need a filter to translate pulses properly. Can you call your cell-phone using On-Hook dialing? I would say there's nothing wrong with the machine. But you'll get blamed for the communication problem in any case. Try manually dialing using On-Hook dialing (turn your Monitor sound up high) and listen for some kind of message. It's a number or line problem. Did they just start requiring an 8 or 9 to be prefix-dialed to get "out?" Or stop requiring it? Maybe there is a prefix number programmed through the default menus that you don't need anymore.
