HUNTSVILLE, AL (July 20, 2005) — Digium Inc., the creator of Asterisk and pioneer of open source telephony, today announced the availability of its second generation firmware for Digium.
The new firmware solution relies less on the server's CPU, therefore reducing CPU overhead and improving performance and increasing channel processing. For example, a dual-processor, 3-GHz 800FSB Intel XEON server with 1MB L2 cache, with a Digium 4-port T1/E1 card, can now process 120 channels with G.729 compression without Digium's echo cancellation module and 150 channels with G.729 compression with the Digium echo cancellation module.
"This development is significant for Digium's Asterisk customers," said Mark Spencer, president of Digium and creator of Asterisk. "There is always room for improvement in technology and we are dedicated to providing our customers with solutions that offer higher quality and reliability than our competitors. Our second generation firmware results in a 67% performance increase over previous benchmarks."
Additional improvements in the firmware include hardware TDM channel alignment (instead of software channel alignment) resulting in greater voice integrity and reliability, master clock source distribution for synchronized timing across multiple cards, assuring synchronization of clocks and increasing reliability and quality of data transmission, zero-latency TDM direct hardware-level cross-connect, support of new echo cancellation module resulting in increased performance, hardware DTMF detection with echo cancellation module and field upgradeable firmware for future updates.
Support and Availability
The Second Generation Firmware for Digium quad span and dual span T1/E1 cards is now available. For more information, please contact sales@digium.com or call 1-877-LINUX-ME. All Digium products are warranted and include installation and troubleshooting support.
About Digium
Digium is the creator and primary developer of Asterisk, the industry's first Open Source PBX. Used in combination with Digium's PCI telephony interface cards, Asterisk offers a strategic, highly cost-effective approach to voice and data transport over TDM, switched, and Ethernet architectures.
Digium solutions reduce the costs of traditional TDM and VoIP implementations through Open Source, standards-based software and next-generation gateways, media servers, and application servers. Digium hardware supports traditional voice protocols, including PRI, RBS, FXS, FXO, E&M, Feature Group D, Groundstart, Loopstart, and GR-303. Data protocols include PPP, Cisco HDLC, and Frame Relay. For packet voice, Asterisk supports IAX™ (Inter-Asterisk eXchange), SIP, MGCP, Cisco Skinny® (SCCP), and H.323 VoIP protocols.
About Asterisk
Code for Asterisk, originally written by Mark Spencer of Digium Inc., has been contributed from open source software engineers around the world. It supports a wide range of TDM protocols for the handling and transmission of voice over traditional telephony interfaces. It also supports US and European standard signaling types used in standard business phone systems, allowing it to bridge between next-generation voice-data integrated networks and existing infrastructure. Using the Inter-Asterisk eXchange (IAX™) Voice over IP protocol, Asterisk merges voice and data traffic seamlessly across disparate networks. While using packet voice, it is possible to send data such as URL addresses and images in-line with voice traffic, allowing advanced integration of information.
