My home phones are not working and I am not sure how to troubleshoot
the problem. I would appreciate some pointers or some help.
The situation and symptoms are as follows.
1/When I pick up the phone upstairs, I can hear the dial tone and I
can make a phone call. That works fine.
2/However, when someone calls me, the phone upstairs does not ring. I
forgot to ask the caller whether they get a busy tone or, a normal
tone, or something else.
3/The phone downstairs does not work at all. I cannot hear dial tone
and I can make or receive calls downstairs.
I suspect that there must be a problem with the phone lines inside my
home. But I do not know how to test these...
Many thanks in advance.
