Works like a charm in Asterisk 18 on Ubuntu Server 24. Only the DAHDI driver needed adding two lines of code before compilation, but it is only because the developers decided to artificially phase out older PSTN cards. Also, if someone finds the sound in connected phones too quiet - use the parameter "txgain" in chan_dahdi.conf. Overall, card is an excellent choice if someone doesn't want to spend a lot and has a motherboard with PCI slot.

I bought the 1 FXO + 3 FXS version, so I can connect 3 analog phones downstream and 1 connection to phone company. I routinely have some trouble with DAHDI properly detecting the configuration when rebooting the Asterisk machine, but I'm not convinced that it is the fault of the card, it might be my configuration. I'm happy with the functionality at this price point.
