Thanks for the quick reply. I have cable internet - very high speed. We set up the Telo in our TV room near a computer line and telephone outlet.
My wife was in the room where the Telo resides and I was in a different room next to a phone when it suddenly quit working. We both noticed it at the same time, as she heard a voice coming from the Telo and I noticed the base of the phone next to me start blinking. I picked up the hand set and it made a strange noise, but nothing worked. Then after our attempts to locate and correct the problem we got no response at all except for lots of messages in my voice mail on line.
Neither of us was doing anything of importance when this all occrued as I was listening to a Youtube video and she was watching a TV program. I suppose some hidden anti malware could be working in the background which suddenly for no apparent reason had decided to block our Ooma dial tone. I don't know. I also don't know what I am supposed to do with the IP address: 172.27.35.1 that you want me to type. Where do I type this? Also, how do I get to the Nework tab you are talking about? I am not a computer expert but I know enough to follow reasonably simple instructions.
