Proteus 7 Customers Respond Positively to Multi-Switch and Multi-Communication Type Reporting

INDIANAPOLIS, July 5, 2011 /PRNewswire/ — CTI Group (Holdings) Inc.
(OTCBB:CTIG), a leading developer of telecommunications solutions for fixed,
mobile and converged communications, is pleased to announce the release of
Proteus® 7 SP1, an upgrade to its fully scalable hosted or premised-based call
accounting solution for mobile, VoIP and PBX telephony systems.

Proteus 7 now includes the full support for extension mobility, in addition to
audio, audio conference, video, video conferencing, mobile and IM. Also, the
ability to partition a single physical switch into a number of logical devices,
auto-learning extensions across a range of switches, enhanced logging of hunt
groups to provide individual station or agent data, and the ability to restrict
logging of groups of extensions via exclude lists.

Todd Justad, Telecom Operations Architect for Network Operations at Citrix
Systems states, “We needed a system capable of collecting call data from
multiple switches in different countries and costing calls using multiple
carriers and currencies. Proteus Enterprise was the only tool on the market that
allowed us to do this and to deliver accurate information and reports from
across the organization.”

Via a configurable dashboard, Proteus will log hybrid environments, where
digital PBXs reside alongside IP PBXs. This helps companies analyse costs and
usage of their voice systems as they migrate from digital PBX to IP PBX; for
example, a reduction in inter-site calls, reduction in international call
charges, reduction in mobile costs through use of softphone or VoIP from
handset.
