OpenVox Introduces ISDN BRI Cards with Echo Canceller

The release of ISDN BRI Cards BE200E/P & BE400E/P has been announced by OpenVox Communications Co. Ltd. The cards will come with a carrier grade hardware echo cancellation module. The advanced on-board hardware echo canceller will allow users to experience great voice quality and stability in the telephony systems. OpenVox is a top provider of the most advanced open source asterisk telephony hardware and software products around the world.

Based on Siemens technology, the new carrier grade echo canceller supports international levels that exceed G.165/G.168. Echo tails up to 128ms or 1024 taps for all voice channels over ISDN BRI lines are therefore eliminated. This also results in no additional CPU load. Superior voice quality on all calls in every single phone system will be therefore ensured by the newly added EC module.

In a release, Lin Miao, president of OpenVox said, “The ISDN BRI asterisk cards have always played an important part in European telephony market. The release of the new products will provide our customers an advanced choice for their telephony solutions. Moreover, all these newly released BRI cards now enjoy a lifetime warranty.”

Miao added the products from OpenVox are of superior quality. The company also provides experienced technical support and service. The company therefore believes it is at the top in the European open source telephony market.

Three main product lines are now being fulfilled by OpenVox. These include Analog, ISDN BRI and PRI cards.  Four new models with hardware echo cancellation modules have been introduced by OpenVox under ISDN BRI. They include BE200P 2 Port BRI Card + Hardware Echo Canceller PCI (News - Alert) and BE200E 2 Port BRI Card + Hardware Echo Canceller PCI Express. The other two models are BE400P 4 Port BRI Card + Hardware Echo Canceller PCI and BE400E 4 Port BRI Card + Hardware Echo Canceller PCI Express.
