Call Screener v4.01 for Agere or LSI or Lucent Chipset Modems – Updated for Windows 10

Call Screener v4.01 is a software app for 32 or 64 bit Windows 7, 8, 8.1 or 10 that blocks unwanted phone calls on a landline phone.  Call Screener requires a dial-up modem that has voice and caller ID capability to be installed on your computer. (Call Screener uses only the voice and caller ID features of the modem — there is no need to “dial-up” anywhere.) When a call is blocked, Call Screener speaks the message contained in the ZapMessage.wav file to the caller. An example ZapMessage.wav file is included in the kit that comes in the download. Also, if you block anonymous calls, Call Screener plays an anonymous caller rejection message that instructs the caller how to remove their call blocking.  Optionally, you can specify a different “call blocked” message for each phone number that is to be blocked.  Documentation is also included in the kit. In addition to being able to block calls by caller number, Call Screener can also block calls by caller name, such as “Card Services” or “800 Service”, no matter what number appears on the caller ID.

Call Screener v4.01 includes the latest features of Call Screener v4, including:

●  The ability to gather from the internet the most complained about annoying callers and to automatically include them in the user’s call blocking list.

●  A button on its user interface to initiate reporting of Do Not Call List violations to the National Do Not Call Registry.

●  Call blocking by caller name as well as by caller number.  Blocking by caller name makes it easy to block all calls from, for example, “800 Service” or “Card Services”, no matter what number appears on the caller ID.

●  A “black list” of caller numbers or names to be blocked.  An individual blocking message can be associated with each number or name.  You are free to create your own blocking messages and to include them in Call Screener.  In addition to caller numbers and caller names you enter, the black list can optionally include blocking of anonymous calls, “out of area” calls, “unavailable” calls, and calls for which no caller ID is received.

●  A “white list” of numbers that are always accepted.  One use of the white list is to include particular numbers from, for example, “800 Service” if you otherwise block those calls.

●  The ability to provide a comment notation in the call block list to the right of a blocked caller number or caller name, which makes the list more compact and easier to comprehend in a single glance.

Changes for version 4.01
New feature: Ability to block all calls except for those on the Accept Always list.
Bug fix: Fixed the Accept Always bug.

Suggested Modems
Modems that I’ve tried and have worked well are the HiRO H50113 USB and the Rosewill RNX-56USB-AG external modems, and the HiRO H50006 and the Rosewill RNX-56AG PCI internal modems. I think the TRENDnet TFM-560U USB external modem may also work, but since I haven’t actually tried one, I can’t vouch for it. I’ve included drivers in the kit that support both caller ID and voice for the HiRO H50113 and H50006 modems.  NOTE: The Rosewill RNX-56USB modem will not work with Call Screener. I have read that there is a bug in Microsoft’s TAPI that prevents outgoing messages from being played when used with modems that have Conexant chipsets, such as the RNX-56USB.

  1. Thanks for the great app!!

    My phone will only block 30 numbers and those bum spammers are generating tons of numbers using VOIP. I am on the FTC “Do not call” list, but that doesn’t seem to make much difference. Call Screener will help tremendously!

    The next step that would be nice is an applet that can record the IP and/or MAC address of the caller using VOIP. We could now trace them and report them to the FTC. It might help.

    Thanks again!!

  2. How to Prevent Windows Update from Updating your Modem Driver

    The modem driver in the kit is an older version (2.2.98) of the driver that supports voice. The current version (2.2.102) of the driver, which Windows installs by default, does not support voice. Here’s how to prevent Windows Update from updating the version 2.2.98 driver to version 2.2.102:

    Bring up the Control Panel, click on “Windows Update”, and then “Check for updates”. Wait for the list of suggested updates to be displayed. Then click on the link for “…optional updates are available.” Right click on the optional update for your LSI modem and click on “Hide update”. After you have done that, Windows Update will no longer try to update the modem driver.

  3. Question about how Call Screener loads the block list. Does it load it into memory when you start the application or when the phone rings? The reason I’m asking is I’m trying to reduce the number of times the phone rings before Call Screener picks up.

    • Call Screener loads the block list into memory when you start the application so it can scan the list quickly and decide whether to answer the phone and block the call.  But the number of rings that occur also seems to be a function of the brand of modem.  Some modems answer after one ring; others, after two rings.  I think the HiRO H50113 answers in one ring, but I’m not sure, because for many years now I’ve been using the Conexant version of Call Screener.


  4. Call Screener would not run under Windows 10 and the operating system was providing no clue. However, right-clicking on ‘Call Screener v4.01.EXE’ and selecting the ‘General’ tab may reveal the cause – if it is there, check the ‘Unblock’ field at the bottom and click on ‘OK’. Call Screener then worked fine for me.

    I am hoping that Call Screener will help me eliminate the few unwanted calls that I still receive, despite having a call blocker installed on the line. I like the idea of giving telemarketers the chance to listen to some nonsense before hanging up. Only fair – I have to listen to them before hanging up.

  5. Out of area calls are logged by Call Screener as a single O. If I add and entry to the block list with O and a number of spaces it blocks all caller id’s beginning with O such as Oak Ridge. Any ideas?
