Old Buckenham telephone call

Who was talking from the phone?
The link below is to a BBC radio programme on BBC Radio 4 extra today that contains an old recording of a lady talking from the telephone box by Old Post Office Terrace

Go about 45 minutes into the programme. Her name sounds as if it was Lancaster. Can anyone tell me more?

Thanks to Jackie Terry and the power of the village Facebook site we have learnt that the caller's name was Margaret Lancaster and she lived at Carr Farm, Old Buckenham. If Jackie remember rightly it was Radio Norfolk that she phoned and the call just went on and on.They used to keep playing it as one of their classic callers. Her husband was Tony Lancaster and he worked for John Alston of Besthorpe Hall. They had a daughter called Denise who lives in Attleborough.
