Do Not Disturb
If you select Enable Do Not Disturb, all incoming calls are forwarded
according to your "Enable Busy Call Handling" settings, described
immediately below.
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 enabled Do Not Disturb.
If you want to use the Auto Attendant/IVR and you don't know the number
of the phrase or menu you want to use, check with your system
administrator.
Number of Rings Before Forwarding
This setting pertains to almost all the options in this window: the number
of times the phone should ring before the system decides to forward the call
to an extension, voice mail, or the Auto Attendant/IVR.
Email Forwarding
To forward email:
1. Select the Enable Mail Forwarding check box.
2. Select the Forward Email check box, and type in the email address to
which to forward the mail.
3. Choose whether you want the original address's mail to be deleted,
treated as new, or treated as read and saved mail after it is forwarded.
