Yet I am not completely happy with them and would like to hear about the competition. Specific complaints include bad ring-detect circuitry (shout into the phone and the board goes off-hook) and the lack of a hybrid circuit to prevent output audio from finding its way into the touch-tone receiver (the board will often not hear a touch-tone from the user if pressed at the same time as speech is being played). The other four-port boards that I know of are the AT&T Voice Power board, and a similar board from Rhetorex. How do these compare? Unfortunately, Rhetorex does not provide Unix drivers.
