Abstract: The method guarantees the reservation of  exclusive  line  at any cases using the detour function between the private  automatic branch exchanges (PABX). The method includes steps; (A)  accessing an automatic detour memory to check the possibility of detour; (B) sending the busy tone when the detour is impossible,  seizing  the detour line if possible and sending the dial  tone  to  seize  the receiver PABX exclusive line; (C) seizing the exclusive line  when the line is free at (A)  step  and  sending  the  dial  tone;  (D) checking the exclusive lien  reserving  data  periodically  on  an exclusive lien  service  modue  of  a  first  PABX  (PABX,A);  (E) checking that the reserved line when the reserving data exist  and checking that the reserver is free; (F) sending the ring signal to the reserver and receiving the dial digits; (G) checking the  hook on or hook flash of the reserver; (H) sending the transfer tone to the receiver when only hook-flash is detected and returning to the step (G).
