I work for a utility in Pa. If it breaks the lines, the power or phone company will pay to fix their lines, the phone company will pay to fix their lines. Some power companies trim regularly, some less often. Phone companies rarely trim anything, anymore. Too many trees, too cheap, not enough workers. In PA there's so many trees dying from this bug or that bug and storms, ice & wind are always dropping trees. The power or phone company doesn't own the trees, but they get stuck trimming to get customers back in service.
