Unusual phone (landline) problem. If you call my house, you will receive on ring and that's it. It's as thou your call has gone into a call blocker. On my end, I do not get a ring, so I'll never know you called. Thinking the answering machine may be messed up and is picking up the line, I disconnected everything. Called my house on my cell, and again, one ring then dead silence. I still have an old 1960's phone, so I plug it in, and it's the only phone connected. I call my number, one ring, then silence. But my cell phone still shows I'm connected. I pick up the old phone, and I'm on line to my cell phone (the line is open.) I haven't tried it yet, but if you call my house, I'll never know it, and the line is open. Now I'm wondering if the phones transmitter is transferring what's said to the calling party...? Let me know if you have any thoughts while I make a tin foil hat.
