Summary: Revised Tariff WN U-4 by Ellensburg Telephone Company for discontinuing busy line interrupt and busy line verification services. The services are discontinued because CenturyLink, as the underlying provider, discontinued the service offering last year. No customers used either of these services in 2016 and they were notified of these service discontinuations via a bill insert. The Kittitas Public Service Answering Point was notified of this change on January 10, 2017.
