Citel Portico TVA Accelerates Enterprise Migration to Centennial's Aptus Service


Centennial Business Solutions (NASDAQ: CYCL) announced today that it has
selected Citel, the VoIP Migration Company(TM) (LSE AIM: CITE.L), to supply its
Portico(TM) Telephone VoIP Adapter (TVA(TM)) for Centennial's Aptus hosted IP
service. This service, combined with Citel's Portico TVA and the BroadSoft, Inc.
BroadWorks(R) enterprise telephony platform, enables enterprises of all sizes to
obtain the feature and cost-saving benefits of Voice over IP utilizing their
existing PBX telephones and wiring infrastructure.

The solution from Citel and Centennial Business Solutions delivers the features
and functionality of VoIP without the costs associated with typical "rip and
replace" VoIP migration solutions. With the Portico TVA, enterprises avoid the
cost of network upgrades, new handsets, and retraining. PBX handsets connect
over existing wiring directly to the Portico TVA, which connects to Centennial's
Aptus network over Ethernet via the SIP protocol.

"Centennial's Aptus hosted IP service is a compelling solution for businesses
that want to add robust features and enhance productivity by keeping workers
connected wherever they may be," said Edward Koerhuis, director of product and
business development, Centennial Business Solutions. "Citel's Portico TVA adds
to the value proposition further by enabling businesses to migrate very quickly
and cost effectively by using their existing infrastructure."

Centennial Business Solutions recently secured its first Portico TVA-enabled
customer, Berrios, Inc., a major retailer with locations throughout Puerto Rico.
Berrios will deploy the Portico TVA at more than 35 retail locations to support
its growing operations and migration to Voice over IP.

"Most enterprises seeking the cost and feature benefits of Hosted IP telephony
are hesitant to throw away their existing PBX handsets in return for a costly
and time consuming upgrade to IP phones and new LAN hardware," said Michael
Burke, senior vice president, Citel. "Portico TVA enables these enterprises to
obtain the benefits of Centennial's Aptus service using their existing telephone
and wiring infrastructure.  We're excited about the opportunity to work with
Centennial Business Solution's sales force to bring the benefits of Hosted IP
telephony to a broad range of customers."

BroadSoft expects its partnership with Centennial Business Solutions and Citel
to accelerate migration to Hosted IP in Puerto Rico and the Dominican Republic.

"We are looking forward to a long and successful relationship with Centennial as
the IP platform provider for its customer solution," said Scott Wharton,
BroadSoft's vice president of marketing. "The combination of Citel's Portico TVA
with our BroadWorks(R) VoIP platform and Centennial's Aptus service provides a
complete hosted telephony offering for every size of enterprise. We are thrilled
to be a part of this integrated approach to VoIP migration."

The Citel Portico TVA is available in digital, P phone, and analog compatible
configurations. It interoperates with more than 65 handset types including Avaya
Definity(R), NEC DTERM, Nortel Meridian(R) and Norstar(R), Panasonic DBS, and
Toshiba Strata DK.
