You need to configure "isdnd" before you can use "isdnphone". Try running
"capitest -u 0 -i 1 -o 1" instead.

Do you have "isdnd" or "Asterisk+chan_capi" running ?
A quicky is to just: "cat /dev/i4b > /dev/null &"
Do any messages appear now?

Not without configuring "Asterisk+chan_capi" or "isdnd".

It might be a problem with the cabling, but try dummy opening "/dev/i4b"
first, and see if messages does not start to appear when you run "isdndecode
-u 0 -i -x -o", and start dialing out.

If the messages you get use TEI 0 then it is P2P_NT you need to setup.

"isdntest" can do some basic testing, but "capitest" is better. "isdntest" is
not installed by default.
--HPS
PS: I recommend you install the SVN version of the driver. It has got a better
echo-canceller than the 1.6.1 version has got.
