I've done a guide on using this function. It's a few years old, but it works. Please take a look at it & try it out.
TO ASSIGN OR QUERY A RE-DIRECTION DN USING AN FFC
1. Take the telephone off-hook, or press the DN key on a digital telephone.
2. Enter the USCR FFC. i.e. “*38”)
3. Enter the station control passcode (default i.e. “1111” , ”1234” or “DN number” etc).
4. Enter the USCR Option Code (as shown below).
5. Enter new RCO if assigning the RCO; Enter re-direction DN if assigning the DN.
6. Place telephone on-hook, or press the RLS key on a digital telephone.
USCR OPTION CODES
Code Used to assign
1 Internal Forward No Answer
2 Internal Hunt On Busy

5 RCO (Number of rings before re-direction)
Note! This applies to code 1 & 3 only.
RDR default rings is as follows..
0 = 4 Rings

2 = 8 Rings
TO ASSIGN OR QUERY A RE-DIRECTION DN USING THE USR KEY
1. Press the USR key on a digital telephone.
2. Enter the station control passcode (default i.e. “1111” or “DN number if it is over 4 digits long”).
3. Enter the USCR Option Code (as shown in the table above).
4. Enter new RCO if assigning the RCO; Enter re-direction DN if assigning the DN.
5. Press the USR key on the digital telephone again.
NB: To change the passcode, enter. *6, PPPP,NNNN,NNNN (default is usually “*6”)
(Where PPPP = Old passcode,1st NNNN = new passcode, & 2nd NNNN = new passcode again)
All the best
