Title: Reset shift call system
Inventor: KINOSHITA KUNIKAZU
IPC: H04M3/42
Filed: 1989-12-20
Abstract: PURPOSE:To improve the convenience of a caller extension by devising the system such that a reset shift call is applicable to other extension whose low- order plural digits of a telephone number differ from those of a called extension. CONSTITUTION:A shift digit number registration means 100 registers a shift digit number RC for a reset shift call. When a called extension 22 selected by a caller extension 21 is busy, a reset shift connection means 200 revises a number of a digit equal to a low-order shift digit number RC of the telephone number of the called extension 22 depending on the number with the shift digit number RC registered already by a shift digit number registration means 100 received succedingly from the caller extension 21 and the arrival of a call to other extension 23 having the telephone number after the revision is tried. Thus, the reset shift call is applicable between extensions whose low-order numbers corresponding to the shift digit number registered in advance in a private branch of exchange differ. Thus, the convenience of use of the private branch of exchange is improved and the flexible operation is attained.
