MY CUSTOMER HAS A MITEL 5000 WITH 8528 SETS.
IF THEY PLACE A CALL ON HOLD, THEN HIT PAGE, THE CALLER IS DISCONNECTED. THEY SAY THAT THEY HAVE TO PLACE THE CALL ON HOLD OR PARK, HANG UP THE HANDSET, PICK THE HANDSET BACK UP AND PRESS PAGE.
ALSO, IF THEY PLACE A CALL ON HOLD THEN SET THE PHONE ON THE DESK INSTEAD OF THE RECEIVER HOOK, THE CALLER IS DISCONNECTED WITHIN SECONDS.
PLEASE HELP
