Telephone problems

Phone rings once only then cuts out

@Brian257 some background details, please. Are you new to Sky landline? Or has your landline with Sky worked up to now? Does your phone plug into your broadband Hub or a wall socket? Is it connected to a wall socket via a microfilter?

Does the connection test here detect any fault? https://www.sky.com/help/articles/broadband-diagnostic-start
