This could be a context issue, I had to fuss with mine to get the
channels working independently too.

I'll try to post the examples tomorrow, way to tired now :).

Okay, that means that Asterisk/chan_capi isn't using a channel at that
time. 
But it does not know about other programs or even other devices on the
ISDN bus.
When the call is coming in, are you sure you don't try to forward it to
more than one CAPI destinations? For each destination, one channel is
needed, even if the call is not accepted.

A dchannel trace might show something.
