I'm too much of a newbie to use a database to hold the configuration
files and besides that I want to manage the files manually until I
know what I'm doing in a gui/database environment.  I don't want to set
up LDAP either at this time, I'm not sure it would give me anything.
I'm not sure what the last error pertains to, again I probably need to
shut something off.  I'm running Asterisk 1.8.3.  I'm concerned about
the signaling errors and not sure what is causing them as my
chan_dahdi.conf appears to be correct.
