SECURITY ALERT:
If you do not manage this feature carefully, its unauthorized use may cause you
SECURITY ALERT:
security problems. For example, someone who knows the TTI security code
could disrupt normal business functions by separating telephones or data
terminals. You can help protect against this action by frequently changing the TTI
security code. You can further enhance system security by removing the feature
access code (FAC) from the system when it does not need to be used (for
example, there are no moves going on at present). Consult the Avaya Products
Security Handbook for additional steps to secure your system and find out about
obtaining information regularly about security developments.
Before you start
Before you can merge a telephone, you must set the TTI State field to voice on the
Feature-Related System-Parameters screen. You also must set the extension to match the
port type of the TTI port making the merge request. For example, a digital telephone type can
merge only to a port on a digital board.
!
CAUTION:
When a telephone is unplugged and moved to another physical location, the
CAUTION:
Emergency Location Extension field must be changed for that extension or the
USA Automatic Location Identification data base must be manually updated. If
the Emergency Location Extension field is not changed or if the USA
Automatic Location Identification data base is not updated, the DID number sent
to the Public Safety Network could send emergency response personnel to the
wrong location.
Note:
You cannot use TTI to change a virtual extension.
