Avaya Modular Messaging Concepts and
Planning Guide
Telephone user interfaces
A telephone user interface (TUI) provides subscribers and callers access
to Avaya Modular Messaging, from a touch-tone telephone.
The Modular Messaging TUI presents two interfaces:
! The caller interface
! The subscriber interface
The caller interface
This interface interacts with unauthenticated callers that can, on
successful authentication, reach the subscriber interface. The caller
interface includes the Automated Attendant, if enabled. With Modular
Messaging, Release 2, the caller interface is also known as the Avaya
Common Caller Interface (CCI). The caller interface can also be extended
with Caller Applications.
Automated
Attendant
The Modular Messaging Automated Attendant greets callers and guides
them through the process of calling subscribers. Administrators can
configure the Automated Attendant to enable callers to dial subscribers by
spelling the name using touchtone keys.
If the called subscriber is not reachable, callers are presented with the
caller interface. Callers can leave voice messages or fax-only messages
for subscribers. Callers calling in to a Modular Messaging—MSS system
can also leave voice-and-fax messages for subscribers. For more
information, see Avaya Common Caller Interface
on page 4-3.
However, if the telephone system is configured to support supervised
transfers, callers return to the Automated Attendant that guides callers
through the process of leaving messages for subscribers. Callers can also
page the subscriber or notify the subscriber, provided the system is
suitably configured.
Callers can also transfer the call to a designated operator, or to a
designated personal operator, provided an active schedule exists for the
personal operator. An operator can be designated for the entire voice mail
domain, and a personal operator can be designated on a per-subscriber
basis.
If the telephone system supports Direct Inward Dialing (DID), callers can
dial the extension number of subscribers, without having to go through
the Automated Attendant. If such callers are not able to reach the called
subscribers, they use the CCI to leave messages for subscribers.
