HC Deb 04 June 1931 vol 253 c350
47. Mr. C. WILLIAMS (for Mr. D. G. SOMERVILLE)

asked the Postmaster-General whether, in view of the errors arising in the working of some of the new automatic installations, the public is safeguarded against being credited with calls which were only productive of wrong numbers being connected; and, if so, how this safeguard operates?


Wrong numbers are rare with automatic operation. If a wrong connection is made, the subscriber should dial "O" and advise the operator of the occurrence in order that credit may be allowed.
