Sangoma Technologies Announces Premium T1/E1/J1 Voice Support For Asterisk And Other Pc-Based Voip Projects

Toronto (PRWEB) February 23, 2005

Sangoma Technologies Corporation (TSXV: STC) (, a leading provider of connectivity hardware and software products for WANs and Internet infrastructure, announces that its family of AFT (Advanced Flexible Telecommunication) T1/E1/J1 voice/data cards are now customized to work with Asterisk, the free Linux PBX software that is revolutionizing telecommunications on VoIP and conventional telephone networks.

Capable of handling both voice and data and supporting all popular open source projects including Asterisk, YATE, SIPxchange, OpenPBX and others, the A101, A102 and A104 offer a new market standard for performance, reliability, compatibility, support and ease of installation. With less demand on the host CPU, Sangoma's WANPIPE® drivers take advantage of the AFT technology to substantially reduce the processing required to handle TDM voice calls. This reduces the CPU's workload and results in fewer dropped calls, less jitter and better voice quality for callers.

"In all companies of any size, telephone connections are at least as vital as the electricity supply," says Sangoma Technologies President and CEO David Mandelstam. "For soft PBX technology to succeed, reliability and perfect voice quality have to be a given, even before a user can begin to enjoy the powerful and customizable features this technology offers. Our role in this enterprise is to provide the quality in TDM interfaces that allow the soft PBX and VoIP community to realize the potential of all their hard work and imagination."

"Sangoma's family of AFT voice/data cards enables it to offer a new price/performance standard that the competition cannot match," says Halo Kwadrat's Vice-President Michal Bielicki - Sangoma's distributor in Europe. "With Sangoma, we expect to both dominate and expand the integrated T1/E1/J1 connectivity marketplace based on their quality and unparalleled technology."

"The true promise of AFT technology lies in our ability to field upgrade not only the device driver code, but the card's FPGA firmware as we improve our TDM voice support," adds Mandelstam. "Projects already under way include hardware level PRI support and true time-slice channelization on-board. These improvements plus others related to echo and codec manipulation can be retrofitted to existing AFT hardware as they become available."

AFT card features:

·    Compatible and Flexible -- Sangoma's voice/data cards are self-sensing for 3.3v and 5v PCI slots and software configurable for T1, E1 or J1. They share interrupts properly between themselves and other PCI compatible devices, supporting unlimited numbers of cards per PC chassis. The AFT series cards all conform to the 2U form factor, both in height and length, allowing users to install many cards in a slimline 2U chassis so as to maximize server capacity.

·     Rock Solid Data Modes -- In mixed voice/data installations, the data streams are separated out in hardware and handled completely independently of the voice channels by Sangoma's standard WANPIPE® data handlers that have been carrying IP traffic for many years. Only the voice-related traffic gets diverted to the Asterisk system. The result is a system that is totally reliable, fast and well managed, while the CPU load is drastically reduced.

·    Certification -- Certification compliance is critical to every Sangoma customer. All Sangoma voice/data cards have undergone CE, FCC part 15 and FCC Part 68 certification, and every board is properly marked.

·    Sangoma Trust and Quality -- As part of its commitment to quality assurance, each Sangoma card is individually inspected and burned-in prior to shipment in protective anti-static wrap complete with cables, manuals and CDs. The result is a very low dead-on-arrival rate and high reliability in service.

Sangoma Technologies' current solution set includes:

·    WANPIPE® internal media gateways, transporting TDM voice, IP data and video over T3/E3, T1/E1, ADSL and serial links ·    High performance and reliable communications modules for OEM projects involving ATM, Frame Relay, X.25, SS7, HDLC, BiSync and other protocols . The WAN Edukit™ protocol teaching tool for educational institutions ·    POS (Point-of-Sale) interface cards for security and customer loyalty applications
