HC Deb 29 March 1950 vol 473 c35W
2. Mr. Carson

asked the Postmaster-General why callers have to pay for more than three minutes on a long-distance call when the exchange concerned omits to sound the warning signal.

Mr. Ness Edwards

A telephone subscriber making a long-distance call is charged according to the time for which the line is held at his disposal. In those rare cases where a subscriber unknowingly extends his call owing to absence of a three-minute warning signal, the question of adjusting the charge will be considered if he reports the matter to the supervisor at the time.
