Avaya IP Office delivers full voice functionality with a comprehensive set of
features. The system can be configured as a voice-only PBX using traditional
circuit-switched lines or as an IP telephony server using high-speed ISDN/PRI
dial-up access and/or direct leased line connectivity.

When acting as an IP telephony server, IP Office supports cost effective
standards-based IP telephony (H323), quality of service (QoS) through DiffServ
(for routing), 802.1p (when used in conjunction with a Cajun® local area
network [LAN] switch), and remote locations connected via Frame Relay.
Voice calls can be allocated dynamically and can -bump- a multi-channel
data transmission from one of its channels as needed to help ensure priority
voice calls get through.

Multiple Avaya IP Office systems can be linked together using a standard data
network, providing limited feature transparency and advanced applications such
as centralized voice mail and call center. The data networking capabilities of IP
Office include Internet or branch-to-branch based routing with firewall-protected
Internet access and integral security. The system supports the QSIG protocol
for improved networking and interoperability.

As a local-area network (LAN) hub, IP Office can connect up to eight PCs to
each other and a router with standards-based directory support for easy
integration into IT environment. Avaya IP Office is complementary to Avaya
switch technology and VPNet® solutions, giving businesses the ability to grow
into converged networks.

The basic system includes a 4-port voice messaging solution and the ability for
users to manage their phone calls through a simple GUI. Additional applications,
such as enhanced (integrated) messaging, web-enabled conferencing, and
customer service (call center) can be added when needed. The Auto Attendant
application enables callers to route their own calls to the relevant
department/person without the need to speak to an operator/receptionist.
Receptions/operators can take advantage of the SoftConsole application to
present a professional view of the business to all callers. TAPI (Telephone
Applications Programming Interface) support enables IP Office to be linked to
Microsoft Outlook and other popular desktop applications for screen pops and
PC-based telephony management.

Avaya IP Office allows users access from desktop computers, laptop PCs, with
individual firewall security and access control.

Investment protection is offered through handsets supported by several Avaya
platforms, and provides a migration path that is forward and backwards
compatible. IP Office supports IP and digital telephone operation, with large
display desktop phones with sophisticated screen-driven feature access. Single
button on/off control is available for selected features for ease of use.
