Q: Why doesn't my Whozz Calling? device block calls?
A: Some Whozz Calling? devices include "Call Blocking". While this does not hang up the phone like a modem (or a person picking up the receiver and putting it back down), it does stop the phone ringing when the phone is plugged into the output jack of the Whozz Calling? device. If your Whozz Calling? device doesn't include Call Blocking, or the wiring requirement is not convenient for your installation, or you prefer ACIDMU to actually hang up the phone to block callers, ACIDMU's "helper modem" feature can help.

A "helper modem" is a plain dial-up modem (it doesn't even need caller id functionality) that ACIDMU uses to hang up the phone for a Whozz Calling? device. One modem is required for each phone line you want to hang up.

To configure a helper modem, open ACIDMU Console to the Devices page. Select the phone line (near the bottom of page) to configure. Click the "Advanced" button. Enable "Use separate modem for hangup" and select the correct serial port. Click the "OK" button, click the "Save" button on the Devices page, and restart ACIDMU Server. Now when ACIDMU needs to block a caller on the edited phone line, it will use the modem.

Be careful when connecting the modem to the phone line and configuring it. You must connect the correct physical phone line to the modem and configure the right modem on the ACIDMU device line or it could hang up the wrong phone line! This can be tricky when using two or more of the same modem on Windows since it sometimes swaps them when the computer is restarted.

Q: Why does the installer say "A Java Exception has occurred" when I run it?
A: You are probably running an old version of ACIDMU. As of version 3.0, this error should not occur. Please download a newer version of ACIDMU from the product page.

If you're unable to run ACIDMU version 3 or later, then please review the following information relevant to older versions:

ACIDMU uses Java, and Java is saying that the version of Java you have installed is too old to run ACIDMU.

To fix the problem, install the latest version of Java from:

NOTE: If you're installing on Mac OS X, install the Java SDK:
All other systems should use the Java JRE (although the JDK will work):

After installing the latest version of Java, start the ACIDMU installer again.
