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?

Maybe the phone itself is having a problem.

He said there were THREE phones having the problem. Do you think that all
three phones are defective ???????????

The caller may not be sending caller-id.
Not all telephone systems have the capability. Plus, there's no requirement
that the calling customer provide it. Some may suppress caller-id and there
are even ways to spoof what's shown on the receiving end.
About 10% of the calls we receive at work show "No data sent," "Not
provided," or "Unknown name."

I don't have a good answer but I see the same happening to my phones
and have narrowed down to some phones picking up the caller id and
sort of preventing other phones from seeing it for that call.
Should be easy to verify if this is what's happening if your grandma
phones memorize the caller ids. Or she could plug in one phone at a
time and verify that each one is capturing the caller id...
