Description:	In case of wrong configuration of chan_dahdi using "#include dahdi-channels.conf" the error messages are different to the same misconfiguration, but with explicitly edited commands. The error messages because of wrong configuration using "#include ..." are not obvious. Example: /etc/asterisk/chan_dahdi.conf ;This is an excerpt from misconfigured chan_dahdi.conf: ........ ; they mean or you know you should change them. ; Next line should be after [channels] instead, here it is misplaced. #include dahdi-channels.conf [trunkgroups] ; ......... This will result in the following error messages from asterisk: /var/log/asterisk/messages: ...... [Oct 28 10:20:24] WARNING[2836] loader.c: Error loading module 'chan_mgcp.so': /usr/lib/asterisk/modules/chan_mgcp.so: undefined symbol: ast_pktccops_gate_alloc [Oct 28 10:20:24] WARNING[2836] loader.c: Module 'chan_mgcp.so' could not be loaded. [Oct 28 10:20:24] WARNING[2836] config.c: parse error: No category context for line 11 of /etc/asterisk/dahdi-channels.conf [Oct 28 10:20:24] WARNING[2836] chan_dahdi.c: Ignoring any changes to 'userbase' (on reload) at line 23. So, in this case, a WARNING only, which is misleading to the casual user (like me). Opposed to explicitly edited, misconfigured chan_dahdi: /etc/asterisk/chan_dahdi.conf ........ ; ;#include dahdi-channels.conf ;Instead of using include, all statements here group=0,11 context=from-isdn overlapdial=yes switchtype = euroisdn signalling = bri_cpe_ptmp channel => 1-2 context = default group = 63 [trunkgroups] ........ This results in a much more obvious error message: /var/log/asterisk/messages: [Oct 28 10:24:07] WARNING[2884] config.c: parse error: No category context for line 22 of /etc/asterisk/chan_dahdi.conf [Oct 28 10:24:07] ERROR[2884] chan_dahdi.c: File chan_dahdi.conf cannot be parsed.  Aborting. The behaviour of using an #include is different to explicitly typed config statements. Worrying ....
