Hi Patrick!
I found a NT unit, made the crosscable and connected the NT unit to the
ISDN Board which is in NT mode.

At the NT unit is the ISDN phone connected. Instead that there is no
signal after lifting the phone there is directly a busy tone.

Any ideas?!

Nope sorry. Check the messages in the asterisk cli or logs. Maybe it tells you what is going on.

Regards,
Patrick
