t might happen that you need to turn off modules you are not currently using or not working on your Asterisk box.

You can edit /etc/asterisk/modules.conf in the <>Modules<> to tell Asterisk not to load existing modules; for example, the following example we do not load modules for the modem:

noload => chan_modem.so noload => chan_modem_aopen.so noload => chan_modem_bestdata.so noload => chan_modem_i4l.so
