Digium Announces New Hardware Products at VON; New Transcoder and Echo Cancellations Cards Improve Call Quality and Communication between PSTN and VoIP Gateways


HUNTSVILLE, Ala. & SAN JOSE, Calif. --(Business Wire)-- March 14, 2006 -- Digium Inc., the creator of Asterisk(TM), and pioneer of open source telephony, today announced the availability of new hardware solutions to enhance Asterisk transcoding and echo cancellation performance for VoIP and PSTN gateways. These new products include the TC400P VoIP transcoding card and the TE420P and TE415P four-port T1/E1/J1/PRI cards with onboard hardware echo cancellation.



"Our product team is always working to develop solutions like these that ultimately further the open source movement in VoIP," said Mark Spencer, president of Digium. "Not only are we constantly striving to improve Asterisk's performance, but we also want to contribute to the overall VoIP experience, while keeping costs low."

The TC400P provides hardware transcoding of VoIP codecs; decreasing Asterisk's work load and providing improved CPU efficiency and an increase in channel density over a software-only solution. The TC400P provides Asterisk with full transcoding support and hardware acceleration for the G.723.1 and G.729A codecs.


The TE420P and TE415P improve upon Digium's existing TE411P and TE406P. These premium interface cards provide carrier-grade echo cancellation, Voice Quality Enhancement (VQE), DTMF decoding, and tone recognition. Both cards minimize loads on the processor and PCI bus, and are designed to perform in the most difficult environments. The TE420P and TE415P support 128ms of G.168 (2002)-compliant echo cancellation across their entire 128 channels.

Digium designed these solutions to be fully compatible with existing software applications and is completely integrated with the Asterisk platform. Additionally, the open source driver supports an API interface for custom application development. All new solutions support industry standard telephony and data protocols, including Primary Rate ISDN (both North American and Standard Euro) protocol families for voice, PPP, Cisco, HDLC and Frame Relay data modes.

Digium will be exhibiting there full line of products including these new hardware solutions at booth #809.
