There were normally four telephones at White House Farm (although there was only one telephone line). A cream old-fashioned finger-dial telephone kept in the main bedroom (the bedroom telephone), a blue digital telephone in the first floor office (the office telephone), a cream cordless telephone kept in the kitchen but used around and outside the house (the cordless telephone) and a fawn digital telephone also kept in the kitchen (the kitchen telephone).
The only telephone with a memory recall feature was the cordless telephone but this had been faulty and was collected for repair on the morning of 5 August 1985.

That answers this thread question.
