This "dahdi_span_assignments auto" stratement was missing in my
installation script.

This one is now:


    DAHDI_MODULES="wctdm24xxp"
    apt-get -s install asterisk-dahdi module-assistant
linux-headers-$(uname -r) dahdi-source
    m-a a-i dahdi
    modprobe ${DAHDI_MODULES}
    dahdi_span_assignments auto

    ... edit asterisk and dahdi config files

    dahdi_cfg -vvvvvvvvv

Thank you very much for letting me know about this dahdi_span_assignments
command.

May I add I've still got no /etc/init.d/dahdi file or equivalent though
dahdi channels seems OK within Asterisk ?
I'll learn a bit deeper into dahdi_span_assignments to clarify my further
questions, if any.
