[SOLVED] No dial tone puzzle I lost home phone dial tone last week. First, I called att service and they said it is an interior wiring problem. I confirmed this by connecting a (good) corded phone in the Network Interface Device. There was a dial tone in NID and I called my home number from my cell. Then I disconnected all phone jacks inside the house and checked any loose connections. There were all good. I finally called att again asked for service inside my house ($70+ hourly rate) to fix the problem. The night before the service appointment the phone line suddenly worked for no apparent reason, so I called off the att service. However, the next morning it was dead again and came back alive one time the same day before went dead since 3 days ago. I have a DSL splitter to a second line and DSL is all functional all this time. What can go wrong and how to attack this problem? It is a puzzle for me. Need some advice. Thanks.
