Table 4-5. modules.conf [modules] section
Option Value/Example Notes
autoload yes Instead of explicitly listing which modules to load, you can use this directive to tell Asterisk
to load all modules that it finds in the modules directory, with the exception of modules listed
as not to be loaded using the noload directive. The default, and our recommendation, is to
set this option to yes.
preload res_odbc.so Indicates that a module should be loaded at the beginning of the module load order. This
directive is much less relevant than it used to be; modules now have a load priority built into
them that solves the problems that this directive was previously used to solve.
load chan_sip.so Defines a module that should be loaded. This directive is only relevant if autoload is set to
no.
noload chan_alsa.so Defines a module that should not be loaded. This directive is only relevant if autoload is
set to yes.
require chan_sip.so Does the same thing as load; additionally, Asterisk will exit if this module fails to load for
some reason.
preload-
require
res_odbc.so Does the same thing as preload; additionally, Asterisk will exit if this module fails to load
for some reason.
indications.conf
The sounds that people expect from the telephone network vary in different parts of
the world. Different countries or regions present different sounds for events such as
dialtone, busy signal, ringback, congestion, and so forth.
The indications.conf file defines the parameters for the various sounds that a telephone
system might be expected to produce, and allows you to customize them. In the early
days of Asterisk this file only contained sounds for a limited number of countries, but
it is now quite comprehensive.
To assign the tones common for your region to channels, you can simply assign the
tonezone using the CHANNEL() function, and that tonezone will apply for the duration
of the call (unless changed later):
Set(CHANNEL(tonezone)=[yourcountry]) ; i.e., uk, de, etc.
However, since signaling from a call could come from various places (from the carrier,
from Asterisk, or even from the set itself), you should note that simply setting the
tonezone in your dialplan does not guarantee that those tones will be presented in all
situations.
