Forwarding All Calls
When you configure your MaxAgent to forward all calls, the information
is displayed in the status bar. For example if you choose to forward all calls
to an auto attendant, is displayed in the status bar.
Forwarding calls to an external number is not allowed in MaxAgent.
Do Not Disturb
If you check Enable Do Not Disturb, all incoming calls are forwarded
according to your Enable Busy Call Handling settings, described below.
Checking Enable Do Not Disturb here has the same effect as clicking the
DND button in the MaxAgent main window.
Busy Call Handling and No Answer Handling
You can use these options to specify how you want to handle incoming
calls when you're already on the phone or when you can't answer the
phone, for example, when you've checked Enable Do Not Disturb.
If you want to use the auto attendant and you don't know the number of the
phrase or menu you want to use, check with your system administrator.
Place call in queue is available only if your system administrator has
enabled queuing for you.
