Chapter 8 PBX Tutorials • Like Example 2, you can also select Direct (if you want the callers from the PBX's extensions to the ISG50's not to go through the Auto-Attendant) or MSN (if you are using BRI line(s) and you want to have multiple subscriber numbers on one port). Note: Like Example 2, we don't use DDI/DID in this type of example because DDI/DID is mainly used for outsiders to call extensions. 8.7 Using Call Features The ISG50 has built-in call features for functions such as call forwarding, call blocking, voicemail and so on. These features can be activated or accessed by dialing specific numbers from the phones connected to the ISG50. The numbers used to access call features are called call feature codes. This section shows you how to customize call features. It also describes how to configure a ZyXEL IP phone (V300 is used in our example) to access voicemail by using the voicemail feature code. See Section 27.3 on page 433 for more information on all call features. 8.7.1 Customizing Feature Codes Click Configuration > PBX > Global > Feature Code to display the codes used for the ISG50's call features. You can change the codes in this screen. Provide the users with a list of the features and corresponding codes. Users on your network can then dial a code from their telephone to activate a specific feature. For example, dialing *96 transfers a call. Figure 126 Server > Feature Code 8.7.2 Using the Voicemail Feature The voicemail feature code as assigned in Section 8.7.1 on page 163 is **. Users can dial ** followed by their extension number to access their voicemail. For example, a caller from extension 1001 can dial **1001 to access voicemail messages. Some IP phones allow you to configure automatic dialing of feature codes to perform common tasks. See your phone's documentation for details. ISG50 User's Guide 163
