6.8 Call Forwarding for Specific Call Numbers
Besides the call forwarding that you can program at your telephone, the system
administrator can program call forwarding where the call number of the caller is
analysed (“SCF: Selective Call Forwarding”). Potentially this could be the reason
why specific calls do not reach you. If you have any questions concerning this func-
tionality, please consult your system administrator.
7. Special Calls
7.1 VIP Call
H*# Z (internal call no.)
For enquiry calls:
GR*# Z (internal call no.)
If you have VIP access rights and start an internal call with
*#, your calls will be
signalled acoustically to internal parties even if they have activated their call pro-
tection (call-waiting protection or call protection). This function is also possible in
a enquiry call.
This also applies if the called party has activated immediate call forwarding.
This feature cannot be used with a SIP terminal.
