Result:
You hear a confirmation tone of two quick beeps, followed by the dial tone. If you are forwarding to another phone, the 5ESS
places a confirmation call to that number; the call does not have to be answered. If you are forwarding to voice mail, no confirmation
call is placed.
Note:
If you get a busy signal after entering the activation code, call forwarding for that condition is already in effect. Enter the
cancellation code for that condition and start over.

To cancel call forwarding for one condition, follow this procedure. Repeat the procedure to cancel additional conditions.
1. Lift the receiver and listen for the dial tone.

Changing Number of Rings Before Forwarding

seconds. You can change the number of times your phone rings (actually, the elapsed number of seconds) before a call is forwarded.
In the procedure below, enter the number of seconds, from the following table, to get the desired number of rings before forwarding (1
ring = 4 seconds):
