WARRINGTON, England, January 25 /PRNewswire/ --

Martin Dawes Systems, an international provider of billing, customer care
and revenue assurance solutions, today announced its appointment as a
supplier to UK mobile operator O2 of billing systems for O2 business,
corporate and SME subscribers.

This follows the successful implementation of an upgraded billing system
based on the company's dise3G solution. Martin Dawes Systems will work with
O2 on developing new software features and functionality to continue to
deliver improvements in billing & CRM functionality.

Dewi Thomas, Managing Director, Martin Dawes Systems said: "This
confirmation of the strategic nature of our relationship cements the close
ties between our two organizations and highlights O2's ongoing commitment to
the highest standards of service for its valued business customers. Now that
we have successfully concluded the implementation, the system will help O2
maintain their deserved reputation for service quality excellence, as well as
deliver the flexibility needed to support new service innovations."

"O2 (UK) will benefit from how we develop and enhance the platform as an
integrated end-to-end solution for managing and growing customer revenue,"
Thomas added.

The recently completed project involved the implementation of the latest
version of dise3G software for use by over 2000 end-users in customer care,
sales and marketing among other areas. O2 UK had previously operated a very
early "green screen" version of the dise software.

The new GUI system transforms how the software is used in the business.
For example, dise3G provides the flexibility to support a wider variety of
marketing initiatives including price promotions and service bundling.
Customer care and marketing end-users benefit from an interface that makes it
much easier to interpret a customer's relationship with O2.

By replacing the older system with dise3G, O2 also can choose to utilise
newly-developed capabilities for managing convergent services, and explore
more self-service account management options. The new system is much more
scalable and resilient, running in a single environment and therefore
delivering further operational efficiencies to O2.

Editors Notes:

Martin Dawes Systems and O2 UK have enjoyed a long strategic relationship
rooted in the foundation of both companies. The original dise software was
developed by and for Martin Dawes Telecommunications, one of the first MVNOs
in Europe. The mobile business was acquired by BT Cellnet, (subsequently
named O2 UK) and Martin Dawes Systems was formed to continue to develop and
provide its dise software to the telecommunications industry.
