HI ALL,
A BUILDING WITH SIX FLOOR WANT EMERGENCY CALL LANDING IN TWO DIFFERENT EXTENSION FOR EXAMPLE
IF ANYONE CALL 555 FROM AN EXTENSION INSTALLED BETWEEN 1ST TO 3RD FLOOR SHOULD LAND IN ONE OF THE PHONE INSTALLED IN EMERGENCY WARD ON 3RD FLOOR.
and
IF ANYONE CALL 555 FROM AN EXTENSION INSTALLED BETWEEN 4th TO 6th FLOOR SHOULD LAND IN ONE OF THE PHONE INSTALLED IN EMERGENCY WARD ON 6th floor.
so that the nearest ward will be attaining the emergency case..
Thanks in Advance
