Hello, I am trying to solve a problem that I can foresee when I deploy Asterisk into a few SOHO situations soon. In Nebraska and in my area of Western Pennsylvania we have violent thunderstorms in spring and summer and sometimes very heavy wet snow in Winter. Both type of event will take out the power of a period of 30sec to 36-hours. So no UPS system would be able to handle a system for over

...ns (in-house) and also consider strongly testing the whole setup in reverse direction by CALLING OUT and asking the other side "how do you hear me ?" j) Also please note that you need to ask your engineers what average DC voltages you should be expecting for off-hook conditions (use a DC 48Volts meter and the excellent guide available on the Wiki page), and also http://www.teracomtraining.com/tutorials/teracom-tutorial-PSTN.htm, and also the expected ring voltage when CO rings the FXO port. Please make sure you know the "names" of the points at which you are testing, so that you...
