Can BT phones move of there own accord?

DCI Ainsley described where the telephones were within the house on the morning of the 7th August 1985:

“In the kitchen, situated on top of a work surface beneath the hatchway leading to the bottle room, was a normal dial telephone, colour white. This was in working order. The handset was found removed from the cradle.  In the company office on the first floor was a blue coloured telephone with a digital display and memory. There is no evidence to suggest this telephone was used on the night in question but it was used by an officer of the Essex Police Tactical Firearms Group after the farmhouse was entered. This telephone will retrieve on the display only the last number dialled which is automatically erased by the next use. Found in the office was a third telephone on a shelf. It is believed that this telephone was from the main bedroom, having been unplugged and the cord wrapped around the set. This cannot be explained but the set and bedroom plug have been checked by telecommunications employees and both are in working order."

You're highlighted bit matches the COA -

'The office telephone was in its normal place.'

There is no reason why the police would move phones after entering WHF.

Yes, but what about the phone on the shelf?

That is one & the same. The office phone was on a shelf in the office.

There would have been a pause in removing the said phones and also taking the trouble to " hide " one amongst magazines----------what was the family doing while this was carried out watching and wondering what " JB " was doing and why ? This carried out while he had a rifle tucked under his arm ?
Remembering that this " phone-swap " went on prior to the family having been killed and possibly after the phone-call from Pamela.
