One Number Access (ONA)
If you are expecting calls that you want to receive regardless of where you
are, you can have the system forward those calls to you. You must enter the
Caller IDs for the calls you want forwarded, and the numbers where you
can be reached.
If the system is unable to connect the call (i.e., can’t identify a Caller ID or
can’t reach you at any of the numbers you specify), the call is sent to your
voice mail.
Before You Set Up ONA
• ONA must be enabled by your system administrator.
• Your Call Handling settings must not conflict with ONA. Specifically:
— Do Not Disturb must be disabled. Otherwise, if your line is busy,
all calls will go into voice mail and not to the ONA forwarding
numbers you specify.
— Enable Call Forward must be disabled. Otherwise, all callswill be
forwarded according to this setting.
See “Setting Call Management” on page 48 for details on these set-
tings.
