Excellence Award for 2005. INTERNET TELEPHONY magazine has been the

   "The VoIP space is hot these days, and it's easy to get caught up
in the hype associated with such a buzzing marketplace. However, the
winners of the first-ever INTERNET TELEPHONY Excellence Award are not
merely "me-too" players. Vodavi has proven to the editors of INTERNET
TELEPHONY that the Vodavi XTS-IP with Digital PathFinder and Discovery
Manager has excelled in the VoIP/IP Telephony industry, and most
importantly, its customers are willing to speak up and offer
themselves as references," said Greg Galitzine, editorial director of
INTERNET TELEPHONY.
   Tony Perez, general manager of Sport Compact Only (SCO), an
Internet automotive parts and accessories store, has implemented these
award-winning Vodavi products to enhance SCO's call center activities.
He stated, "Since implementing Vodavi solutions, we have achieved a
significant increase in customer service based on satisfaction reports
with our current Internet customers. The flexibility and reliability
of using converged digital and IP technologies lets our sales staff
work at home on weekends using remote IP phones thus allowing us to
cost-effectively extend our hours of operation, increase sales,
improve customer service and keep a leg up on the competition."
   "We are pleased that the editors of INTERNET TELEPHONY selected
the XTS-IP for this award," said Gregory Roeper, president and CEO of
Vodavi. "The XTS-IP family of communications systems supports
converged digital and IP applications and offers enterprises the
flexibility necessary to quickly adapt to changing business
environments." He added, "We also appreciate the inclusion of Vodavi's
ancillary product offering in this award; specifically, the Digital
PathFinder and Discovery Manager, which are extremely popular
solutions for comprehensive voice processing, advanced messaging and
automatic call distribution solutions that businesses use for
maximizing phone system investment, improving productivity and
cultivating additional revenue opportunities."
   "The editorial staff of INTERNET TELEPHONY magazine is proud to
announce the winners of the first-ever INTERNET TELEPHONY Excellence
Awards. These companies are as varied as there are products that fit
under the IP telephony umbrella. But the one thing that binds them all
together is that they all excel at delivering solutions that solve
their customers' needs," indicated Rich Tehrani, editor in chief of
INTERNET TELEPHONY.
