'group = 63' is a work around an old (and long-ago fixed, I believe) in
chan_dahdi (or maybe chan_zap - and never made it to chan_dahdi?). You
can just write 'group = ' instead to reset the groups.

It would be even nicer to write the above as:

switchtype = national
signalling = pri_cpe
dahdichan => 1-23

('dahdi-span-1' is an arbitrary title). This "only" works for Asterisk
>= 1.6.0, and thus I never got to switching dahdi_genconf to use it.
