Chapter 29 Extension Management
• Call Forwarding - set up call forwarding rules for the individual extension based on the
following criteria:
• Your extension is busy.
• You turn on DND (Do Not Disturb). You can set up a list of telephone numbers, referred to as
the White List that ignore DND.
• Unconditionally, forwards all calls to a specific extension or your voice mail.
• There is no answer at your extension. This also allows you to set up a Find Me List, which is a
list of phone numbers where you might be located.
• Call Blocking - set up a list of telephone numbers that you don't want to receive calls from. Or,
stop calls without caller ID from reaching your extension.
• Voice Mail Forwarding - Configure the ISG50 to forward your voice mail messages to your
email account.
