i've installed several Asterisk systems in Shanghai & Beijing.

you might want to comment out all other modules in
/etc/default/zaptel except for wct4xxp (if that's
the only zaptel card you have).

this looks right. however crc4 is optional. you have to
check with the phone company. sometime they do require
it other time they don't. it's not very consistent.

red alarm usually means there's no clocking signal.
check all your cables (crossover vs straight through)
if the cable's good. call phone company and complain.
in my experience 9 out of 10 time we have to call
phone company and complain.
