Definition  
All calls for the ISDN port can be forwarded. Three different types of call forwarding (CF) are available:
 •   Call forwarding unconditional (CFU)
    All calls for the ISDN port are immediately forwarded to any port.
 •   Call forwarding busy (CFB)
    Same as CFU but only if the line is busy.
 •   Call forwarding no reply (CFNR)
    Same as CFU but only if the call is not answered within a specified period (15 s).
