Can anyone tell me why landline telephones wouldn't be getting information on the caller id screen when someone calls?
My grandmother has been having this problem. She says it started months ago after a storm. Most of the time the caller ids work, but every once in awhile they don't. Like the other day, someone called while I was there but nothing showed up on any of the caller id screens. But someone had called two hours earlier and the information had shown up.
She's had problems with her phone line in the past where there would be no dial tone. It was always something outside, usually on her property. She has DSL and there haven't been any problems with that. But as I'm writing this I remembered something. When I plugged in her phone at the computer desk, I don't remember there being a DSL filter anywhere. Could that be causing the problem? There used to be one there but someone could have removed it. So far, three cordless phone displays were damaged so something is going on. Basically, the displays were all garbled so you couldn't tell who was calling.
It would be nice to get an idea of what the problem is and if it's located inside or out. Any ideas?
