Sangoma’s award winning analog telephony cards are renown for their premium quality and dependability and are powering the world’s SMBs and SOHO businesses who still rely on analog telephone lines for primary access to the PSTN. They are also the most flexible on the market, with superior compatibility in most commercially available servers and motherboards, and supported in most Linux and Windows operating systems. They are the number 1 choice amongst Asterisk, FreePBX, and Voice API integrators.

Choose between our scalable A200 and A400 cards for 2-24 analog ports on a single interface slot on your server! Simply add a remora daughter board to expand up to 24 ports. That’s up to 24 simultaneous PSTN calls. Their modular design lets you choose between interchangeable FXO or FXO modules to create your own channel requirements. And for lower density applications, Sangoma’s B600 analog card offers 4 ports FXO and 1 FXS. All our A200, A400 and B600 analog cards offer optional On-board telco-grade echo cancellation for superior audio quality as well as reduced CPU usage providing optimized system performance.

A key component driving the success of our cards is the Wanpipe device driver. Not only does it function as a robust device driver, but also offers a suite of diagnostic functionality, such as line voltage statistics and also audio tracing!
