Nope. This doesn't make any sense, Doug. It's not a voltage differential that causes a phone system to kick a line into an engaged state. In fact, it is the characteristics of the tones themselves. (If a person could generate the appropriate tones with the human voice, the phone system would in fact dial.) What does this mean? I can think of three possible situations: 1) The local phone system has problems with its monitoring sensitivity. 2) The MHz is not generating signals at the appropriate level. 3) The MHz DSP is generating skewed frequencies. I would think the first is most likely, since it seems to be the only real variable here. -Michael
