HC Deb 30 July 1965 vol 717 c187W
Mr. Astor

asked the Postmaster-General whether he will arrange for details of the individual trunk numbers called to be shown on the subscribers' accounts.

Mr. Benn

No. To provide this detail for all calls would add substantially to the cost of the telephone service. Details about individual calls made via the operator are given freely on request, and details of all such calls can be had as a regular arrangement for a small charge. Dialled trunk calls are recorded on subscribers' meters in chargeable units and no details of individual calls are available, but meters rented from the Post Office and installed at subscribers' premises may provide a useful check.
