This off and on problem won't go away. I'm thinking my lines are functional about 3/4ths of the time. As soon as you think it's fixed, the problem returns.

Now, for the first time, the problem has reversed itself. I'm unable to call out. Instead, I get a fast busy on my end trying to dial someone else.

We have a major winter storm approaching and I have no outgoing phone service and marginal incoming.
