I am not familiar with how the /usr/sbin/zapconf tools works, but with
dahdi_genconf in DAHDI, E1 spans default to use CRC4. This covers the
majority of users.

I did not see any way in /etc/dahdi/genconf_parameters to control the
output of the CRC4 line.

My opinion is that you did exactly what you needed: run zapconf to get
sensible defaults then edit the output file for your specific provider.

Cheers,
Shaun
