The Hiding Caller Information is used to suppress the transmission of Quadro user information depending on the called destinations. When this service is activated, "Unknown" or "Anonymous" (or similar text, depending on the type of the phone) will be displayed on the called destination phone for outgoing calls from the current user of Quadro to the selected destination.
Attention: Using "Block Last Caller" operation (see Feature Codes) from the handset for the caller with the hidden caller ID (for example, anonymous@anonymous or similar) may block all unknown callers.
The Enable Service checkbox selection hides the information of current extension when calling to the corresponding Address listed in the Caller ID Based Services table.
Note: Even if the Hiding Caller Information service is enabled, it shall work only for internal PBX calls and SIP calls. If you call through FXO/ISDN port to a PSTN number, the called party will still see your caller ID. To hide your caller ID for PSTN destinations, contact your PSTN operator.
