Call Screener is a software application that blocks
unwanted telephone calls. It runs under Windows XP SP3,
and requires a dial-up modem that that has voice and
caller ID capability to be installed on your computer.
When a call is blocked, Call Screener speaks the message
contained in the ZapMessage.wav file to the caller.
An example of a ZapMessage.wav file is included in this
kit. The format of the ZapMessage.wav file may be
8 kHz, 16 bit mono PCM, or 8 kHz, 8 bit mono CCITT u-Law.
Some other formats may also work, but some do not.
To install Call Screener, create a folder for it, and
copy the files included in the kit into that folder.
See the example Block.txt and Accept Always.txt files
for a description of the formats of telephone numbers.
Some dial-up modems that have worked well for me are the
Rosewill USB RNX-56USB, the Zoom 3025C, the AOpen FM56-PX,
and the Best Data 56HP92-PCT. The Rosewill is an external
modem that plugs into a USB port, and the others are
internal PCI modems.
New in version 1.8: In version 1.8 I added a separate
anonymous caller rejection message, AnonCallerMessage.wav.
As with ZapMessage.wav, you can replace it with your own
