Digium® Releases Asterisk® 1.8, the Newest Version of the World's Most Widely Used Open Source Telephony Platform
Incorporates more than 200 notable new features into the software that has received more than two million downloads over the past 12 months
Technologists working with small and large businesses, government agencies and municipalities, call centers and carriers have downloaded Asterisk more than two million times over the past 12 months. It can be used to create nearly any type of phone system or voice application, with some of the most popular uses being IP PBXs, voice gateways, voicemail, interactive voice response (IVR), conference bridges and automatic call distributors (ACD) for call centers.
"Asterisk 1.8 is the first Long Term Support release since version 1.4," said Russell Bryant, Digium's lead Asterisk developer. "It includes hundreds of enhancements, many of which will help community members building large-scale solutions. The Asterisk community has, as always, been absolutely integral in the development of this major release. Now that it's available, we're rolling our development resources to work on the planned set of Asterisk 1.10 features."
Stefan Wintermeyer, founder of AMOOMA GmbH, a German systems integrator specializing in Asterisk, contributor to Asterisk 1.8 and Digium partner, commented: "The new ISDN features in Asterisk 1.8 are a big step forward for the European Asterisk community. We've been waiting a long time and are pleased that Digium went the extra mile. Even without the ISDN enhancements, the pure performance jump in 1.8 is significant. We can save money on hardware because more calls can be handled by a single Asterisk installation."
