Good stuff
I bought this as a replacement for a water damaged card of the same type. It's predecessor had been in use continually for nearly 3 years without an issue. Fortunately, only this card (the most expensive component and not available locally) was damaged by the water leak. VoipSupply had the card in stock and I received the new one the next day. Plugged it in, the server came up and all is good. BTW, even though the old card still did not work that day, it apparently dried out on its trip to Sangoma repair who could find no issue with the card. Now I have a spare.

From order to installation...seamless.
Sangoma cards are excellent and have the best echo cancellation. Try these cards and you may find they are what you will use from then on. VoIP Supply always gives me great dependable service.

Card worked flawlessly. Accurate documentation. Manufacturer quite helpful.
I installed this card into a Trixbox server. After reading the documentation on the card from Sangoma I ran the setup utility that Trixbox told me to. Comparing the docs with the cut sheet sent by my provider answered all of the setup questions. I plugged in my PRI after installation and simply started making phone calls. Worked flawlessly and the calls sound spectacular. I would highly recommend this card. VoIP Supply was very efficient in helping me home in on the right hardware. A pleasure doing business with them.
