Before Using
Blocking Nuisance Calls
With the FOMA terminal, you can use the following functions to block nuisance
calls or malicious calls such as “one-ring calls”.
Blocking Nuisance Calls
Function name See page Description
Ringing time
Reject unknown
Call setting w/o ID
Call rejection
Bar nuisance call
service
Sets the FOMA terminal not to start the ringing operation until the set
period has elapsed. You can make a setting so that the missed call
record will not list incoming calls that do not meet the set ringing time.
This is an effective countermeasure against “one-ring calls” because
no missed calls with short ringing time are recorded.
Sets the FOMA terminal to reject incoming calls from the phone
number not stored in the phonebook.
This function is valid for callers whose phone numbers are notified. To
reject incoming calls from callers without sending their phone
numbers, set “Call setting w/o ID”.
Sets the FOMA terminal to reject incoming calls from callers whose
phone numbers are not notified.
This function rejects or accepts incoming calls depending on the
reason for no caller ID. Such reasons include “Not supported”,
“Payphone” and “User unset”.
Sets the FOMA terminal to reject incoming calls from specified phone
numbers. Incoming calls from those specified numbers are listed in
the received calls record.
This function is valid for callers whose phone numbers are notified. To
reject incoming calls from callers without sending their phone
numbers, set “Call setting w/o ID”.
By storing a number to be blocked immediately after receiving the call,
the FOMA terminal plays an announcement and rejects the future
calls from that number. Since such calls are blocked through the
mobile phone network, they are not recorded in the received calls
record of the FOMA terminal. Even if you receive calls from the same
phone number without caller IDs, the FOMA terminal rejects those
calls.
A separate subscription is required (subject to the monthly charge).
