Initiating an External Call with Calling Line Identity Restriction
If you want to prevent your next communication partner from seeing your phone number on his phone display, you can suppress the phone number display to your communication partner.
Proceed as follows:
•Using a character string on the internal phone
•Using the menu/function key on a system phone (optional, see the phone manual)
Requirements:
•The CLIR (calling line identity restriction) service feature has been enabled by the network operator.
1.Pick up the receiver.
2.Dial *31#.
3.Enter an external number. Possible entries:
External number (for exchange line request type Internal phone: with preceding exchange line access number)
Short code number (for exchange line request type Direct exchange line phone: with preceding **)
Once you have finished dialling the phone number, the subscriber will be called.
The phone number display suppression has been enabled for this call.
Note: Note. You can also use this function on analogue phones, where it can be performed via the T-Net function key/menu (optional, see manual for the phone).Note: On some ISDN phones and system phones, this function can also be called via an existing function key or via the menu (optional, see manual for the phone).Note: If an emergency number is called while calling line identity restriction is enabled, calling line identity restriction is disabled so that the emergency service can identify the caller.Note: The feature code (keypad) to execute the function, as defined in the PBX, may differ from the requirements of the network provider. In case of malfunctions, ask your network provider for the required feature code (keypad) and change the setting. If you want to use the feature directly on the exchange line instead, the subscriber needs the authorisation for configuring features to be configured by the network provider.
