Using Diva Client CallGuard

The Diva Client CallGuard allows you to protect your ISDN connection from unauthorised use and thereby to control your ISDN charges.

With the Diva Client CallGuard tool, you can:

• Enable or disable forwarding of calls
• Allow or block incoming calls
• Allow or block outgoing calls
• Ask for confirmation before accepting an incoming call of a specified number
• Ask for confirmation before calling a specified number.

In order to use Call Guard, first make sure that you have the latest version of the driver installed. 

Then proceed as follow:

Step 1. In the Diva Client Program Group select Diva Client CallGuard
