• System OAI Third Party Call Control (Level 2 OAI): In addition to the call manage-
ment tools allowed in System OAI Events, System OAI Third Party Call Control is a
system-level communications TSAPI protocol that allows command-oriented tools to
be developed for the system. Contact Inter-Tel for more information regarding these
products.

in a network using analog Audio Messaging Interchange Specification (AMIS) proto-
col. Digital AMIS is not supported.
Access to the Features
Inter-Tel endpoints have feature buttons that allow one-button dialing of feature codes. Infor-
mation is programmed in the database to determine the arrangement of the feature buttons and
their default values. As appropriate, some of the endpoint feature buttons can be designated as
user-programmable buttons. See page 154 for more information.
Special Button and Hookflash [Recall]
Depending on the feature and system programming, users can either enter feature codes imme-
diately after lifting the handset or while on-hook, or they must signal the system before enter-
ing the feature code. Inter-Tel endpoint users signal the system by pressing the Special button,
which is represented by on the endpoint. Single line DTMF endpoint users perform a
hookflash [recall in Europe], by pressing then quickly releasing the hookswitch. If the user
does not enter a code or begin dialing before the Dial Initiation timer expires, the system sends
reorder/fast-busy tones.
