This WAS the message "Phone makes terrible sound w/ ans machine"
I am now checking the phone line, but dont have one of those little LED testers. The green and red wires are connected to the correct screws on both ends, but there could be a splice in the crawl space under the house, and I am not crawling under there in this cold weather.
I have a digital, and an analog Multimeter. How can I test to be sure the polarity is correct using either of these meters?
Thanks
Mark
