HC Deb 12 July 1920 vol 131 c1997W
Mr. RAPER

asked the Postmaster-General why, in the case of firms and individuals who have two or more telephone lines attached to the same Post Office exchange, trunk calls which come through for a line already engaged on a local call cannot be switched on to a disengaged line?

Mr. PEASE

It is the practice in London, if a subscriber has two or more circuits to the same exchange, to effect an incoming trunk call over any circuit of the group which may be disengaged provided that the subscriber has agre,d to the assignment of consecutive numbers on the switchboard to his circuits, and has not asked that one or more of them may be reserved for local calls. It is not practicable in London to adopt a similar course when the numbers are not consecutive, although it has been found possible to do so at some provincial exchanges.
