Wanpipe install for Sangoma

Sorry, Im pretty slow with Linux.

AsteriskNow install. As of the date of this post I jsut download the most current version.

Installing Sangoma A200.
Have wget wanpipe drivers.
Stuck at defining dadi source directory. nothing in /usr/src/ during ./Setup dadhi

Unless im confused, dadhi is installed already. because the service is running, but I dont know what do from here…

Many thanks in advance

I think it is looking for the directory containing the source files for dahdi, which would not be by default in AsteriskNow.
