Hello, After not being able to deal with the echo problems SPA3102 has, I decided to return to x100p as my FXO gateway. I have no echo at all or hangup problems, but my box freezes after some time. The web interface will stop responding, no calls can be made or received ( Nothing is heard when I dial a number) but the CLI will work (I can login on the box). I don't know the nature of the problem but I know it is caused by the card. Is it an IRQ problem? Something else? I would buy another brand of card but I don't know if it is an issue on my motherboard or my card.
