jkroon, The attached patch (which is also on my dahlin-298-1 branch on git://github.com/sruffell/dahdi-linux ) will hopefully allow us to see the transitions the ring detector is going through.

I would load the driver, then enable debug "echo 1 > /sys/module/wctdm24xxp/parameters/debug" and you should see output like:

> wctdm24xxp module won't pick up incoming ringing since upgrading to dahdi-linux 2.6.1.
> After discussion with sruffel on #asterisk and a bit of git bisecting the quilty commit is this one:
> df509300791f1bb5b4b652c2adcfbcc016f789e7 is the first bad commit

>     wctdm24xxp: Use time interval for debouncing FXO ring detect.
>     
>     Do not assume the ring detection function is called for every frame.
>     Also change the debounce logic to a state machine to clarify what state
>     a port is in and unify the technique for debouncing the various signals.
