Sangoma Extends GSM Mobile Connectivity to IP-PBX Market

TORONTO, ONTARIO–(Marketwire – Jan. 26, 2012) – Sangoma Technologies Corporation (TSX VENTURE:STC), a leading provider of hardware and software components that enable or enhance IP Communications Systems for both voice and data, today announced the release of its W400 GSM Board. The latest addition to Sangoma’s award-winning family of gateway solutions, the W400 provides mobile network VoIP and SMS gateway connectivity for Asterisk-based IP-PBX systems, and Sangoma will be expanding support for other open source and proprietary IP-PBX platforms in the coming months.

“In the European, African, Middle Eastern, South American and Asian Pacific markets, it is very common for fixed-line to mobile calls to be priced much higher than mobile-to-mobile calls,” said Julien Nephtali, field application engineer at Sangoma. “The W400 provides a simple and cost-effective solution that provides the hardware connectivity from an IP-PBX to the wireless network, and also works in concert with IP-PBX intelligent routing capabilities to minimize calling and messaging costs by selecting the least expensive routing path.”

Employing Sangoma’s highly reliable GSM technology, the W400 GSM Board supports Quad-Band EGSM frequencies for worldwide compatibility with wireless carrier networks. The W400 is a PCI Express (PCIe) compliant board that works with Asterisk DAHDI drivers and has integrated Asterisk Manager Interface support to facilitate integration in open source IP-PBX solutions.

The modular design of the board provides from one to four GSM ports. Each GSM port operates as an independent mobile interface that supports voice and SMS access to and from any PBX extension or device within the IP-PBX network.

The unique design of the W400 board provides front access to the wireless SIMs enabling maintenance personnel to change SIM cards without the need to open the server, or impact any of the remaining GSM modules on the board, ensuring maximum uptime and flexibility in mobile service access.

“The ability to select a mobile or fixed-line for outbound and inbound calling can translate into significant cost savings for any business, and the addition of SMS gateway capabilities delivers additional communication options without the cost for additional hardware interfaces,” concluded Nephtali. “Whether deployed by the enterprise, or by a mobile service provider, the resulting operational savings can have a substantial impact on the bottom-line.”

Sangoma provides an industry-leading solution portfolio that enables the interworking of a wide variety of disparate TDM and IP networks, clouds, protocols, services, devices, and applications. Its portfolio includes award-winning voice and data boards, transcoding and gateway software, and standalone gateway appliances, designed for simple integration with open source and closed source IP PBX applications.
