Digium® Experiences Growing Global Demand for Asterisk® Open Source Telephony Solution

Two Million Digium Users Make Asterisk One of the Most Successful Open Source Initiatives Ever

VOICECON SPRING 2007, Orlando, Fla. — March 6, 2007 — Digium®, Inc., the Asterisk® company, today announced continued strong global demand for its Asterisk open source telephony solution. Digium solutions are now deployed in government, business and education environments in 140 countries across North America, South America, Europe, Asia and Africa.

Asterisk's mature feature set and flexible open source license have led to rapidly growing adoption worldwide. Recent Digium deployments include The University of Pennsylvania; the city of Pforzheim, Denmark; Sam Houston University; Ntegrated Solutions; the city of Schoten, Belgium; Iowa City Carousel Auto Group; Anderson Associates Architects; and IT Connection, a Russian retirement funds company.

"More than 2 million users have embraced Digium's open source technology, making Asterisk one of the most successful open source initiatives to date," said Danny Windham, CEO of Digium. "We continue to see tremendous interest in Digium solutions and ways in which Asterisk can be adapted to meet the dynamic needs of today's growing businesses."

UnWired Buyer, a company that delivers real-time, interactive mobile notification and transaction services, recently used Digium to develop an award-winning Asterisk application for eBay. Using UnWired's application, eBay users can now bid on items from their mobile phones and receive reminders so they don't miss out on the action while they are away from their computers.

"We looked at a couple of other popular commercial providers, but none of them could really solve our problem," said Eric Smith, president and CTO of UnWired Buyer. "With Digium and Asterisk, we went from proof-of-concept to application delivery in just four months. That would have been impossible with a closed source platform."
