Let’s connect to the Asterisk console:
sudo asterisk -rvv
Let’s see what modules are already in use:
module show
Files of modules with the extension * .so are in the directory /usr/lib/asterisk/modules/
To load and unload a module, commands are used (the module name is specified without a file extension, for example, not chan_sip.so, but chan_sip):
module load NAME module unload NAME
In order for the necessary modules to be loaded automatically when starting Asterisk, they must be specified in the file /etc/asterisk/modules.conf, for example, open it in the text editor nano:
sudo nano /etc/asterisk/modules.conf
You can enable the autoloading of all existing modules in the folder /usr/lib/asterisk/modules/:
[modules] autoload=yes
And then we can exclude unnecessary ones using the following commands:
noload => module.so
Either prohibit downloading all and specify only those that are needed, for example:
;SIP VoIP driver load => chan_sip.so load => res_rtp_asterisk.so load => app_dial.so load => bridge_simple.so load => res_features.so load => res_musiconhold.so load => res_adsi.so load => pbx_config.so ; List of required codecs load => codec_a_mu.so load => codec_adpcm.so load => codec_alaw.so load => codec_ulaw.so load => codec_gsm.so load => codec_ilbc.so load => codec_lpc10.so ; If you use Dahdi cards for analog lines load => chan_dahdi.so ; Call parking load => res_parking.so ; Below are the modules I needed when setting up call recording ; требуется если используется res_monitor.so load => func_periodic_hook.so ; Required if res_monitor.so is used, the function STRFTIME load => func_strings.so ; Required if res_monitor.so is used to determine the number, function CALLERID load => func_callerid.so ; Required if res_monitor.so is used for MixMonitor load => app_dial.so ; For recording calls load => res_monitor.so ; To support WAV format load => format_wav.so ; For MP3 format support load => format_mp3.so ; To record statistics of calls to MySQL database load => cdr_mysql.so ; To enable SNMP functionality, for example, to collect statistics by various monitoring systems load => res_snmp.so ; To make calls from the context of the placed files to the directory /var/spool/asterisk/outgoing/ load => pbx_spool.so
To apply the changes in the /etc/asterisk/modules.conf file, execute the command from the Asterisk console:
module reload
If necessary, you can reboot Asterisk as follows:
sudo service asterisk restart
