Is there any way (even a brute-force workaround) to assign a unique ringtone to "No Caller ID"?
Manually assigning a ringtone to all contacts and setting the default ringtone to something different is not an acceptable solution to the problem, because both unknown callers and No Caller ID callers will use the default ringtone. I would like a ringtone that's unique specifically for No Caller ID. Thanks!
