dahdi-channels.conf is generated by dahdi_genconf so as to not accidentally overwrite chan_dahdi.conf. You should #include dahdi-channels.conf inside of dahdi_genconf.  You can use #include's in all Asterisk config files. Various asterisk distributions break out conf files into multiple files using includes for compartmentalization and ease of user customization.

You should be editing whichever file contains the options you need to edit. You shouldn't have duplicated settings between the two files - if you do, you should resolve that.

You should make sure the missing channels are configured appropriately in either chan_dahdi.conf or dahdi-channels.conf files.
