You can use “ Not Block incoming! “ at settings window to see the status of last call to check if there are any mistakes of settings. We have received feedback from many users so far. The following are the common questions.
- Misunderstood an Unknown Call is a number which is not listed in the address book and no numbers are registered in the Filter List.
The incoming number is not registered in the Filter List. Concerning reports about transferring to voice mail, the reason for the most cases are because CallFiter does not block incoming.
- The check box of block incoming is OFF.
Sometimes failed to block incoming.
There are some case of failure due to the load of the phone, condition and timing. If you delete entering number (beginning part match) or incoming numbers not in your address book, the failure may occur less frequently.
When incoming is blocked, the ring tone becomes silent.
It may happen, if you have applications for incoming block or changing ring tone. Please uninstall applications related the functions of incoming.
Sometimes when incoming is blocked, ring tone sounds just for a second.
Because the process is done after incoming is received, ring tone may sound for a few seconds. If you select the ring tone as no sounds for a couple of seconds, it may be avoided
If I set to block unknown calls, calls from public phones are also rejected.
There are three types of unknown calls. “anonymous caller” “call from a public telephone” and “call from undetected areas” . Current telephone programs cannot distinguish these three unless carriers modify them. If you reject unknown calls, please note that you also block calls from public telephones and calls from undetected areas such as international calls.
