§ Major Tryon
The personal call facility is available in all the telephone services between Great Britain and other countries, both European and extra-European. In the services with European countries there is an additional charge for this facility of one-third of the ordinary rate for a three-minute call. This charge is fixed by general international agreement, 1608 and no modification of it is contemplated. In the extra-European services the ordinary rates are on a higher scale and the personal call facility is offered without any additional charge.
