My practice of manual loading of needed modules only.
Change ‘autoload=yes‘ to ‘autoload=no‘ in /etc/asterisk/modules.conf .
Restart Asterisk – Asterisk CLI> core restart now (remember that it will cancel all active calls).
Login into Asterisk console (root# asterisk -rvvvvvvv). Then load modules manually:
Asterisk CLI> module load app_dial.so
Asterisk CLI> module load app_playback.so
Asterisk CLI> module load chan_sip.so
Asterisk CLI> module load codec_alaw.so
Asterisk CLI> module load codec_gsm.so
Asterisk CLI> module load res_rtp_asterisk.so
Asterisk CLI> module load res_musiconhold.so
Asterisk CLI> module load func_dialplan.so
Asterisk CLI> module load pbx_config.so
Asterisk CLI> module load format_sln.so
Asterisk CLI> module load format_wav.so
Asterisk CLI> module load format_gsm.so
Asterisk CLI> module load app_record.so
A nice help for modules being used is ‘Asterisk CLI> module show‘ . This is mine:
Asterisk CLI> module show
Module Description Use Count
res_musiconhold.so Music On Hold Resource 0
app_dial.so Dialing Application 0
app_playback.so Sound File Playback Application 0
chan_sip.so Session Initiation Protocol (SIP) 0
codec_alaw.so A-law Coder/Decoder 0
codec_gsm.so GSM Coder/Decoder 0
res_rtp_asterisk.so Asterisk RTP Stack 0
func_dialplan.so Dialplan Context/Extension/Priority Chec 0
pbx_config.so Text Extension Configuration 0
format_sln.so Raw Signed Linear Audio support (SLN) 0
app_record.so Trivial Record Application 0
format_wav.so Microsoft WAV/WAV16 format (8kHz/16kHz S 0
format_gsm.so Raw GSM data 0
13 modules loaded
Asterisk CLI>
If you need AEL, you have to load 2 modules (in shown sequence):
Asterisk CLI> module load res_ael_share.so
Asterisk CLI> module load pbx_ael.so
The best practice is to configure /etc/asterisk/modules.conf according to its syntax, to prevent manual loading of modules each time your Asterisk PBX starts.
Your installation may need other modules as well.
