Asterisk 11, modules, which have to be loaded for other basic modules to work properly.
preload => res_http_websocket.so ; for chan_sip.so load
preload => res_speech.so ; for res_agi.so load
preload => res_agi.so ; for app_stack.so load
preload => res_monitor.so ; for app_queue.so correct load
preload => res_ael_share.so ; for pbx_ael.so correct load // also works without this,
; but WARNING while loading
Asterisk has a nice function PITCH_SHIFT, which can modify caller’s/callee’s voice. Let’s imagine, we have a system without autoloaded modules, and we need to find which module provides this function.
1. Go to the astmoddir (I have a Debian system):
cd /usr/lib/asterisk/modules
2. Find.
root@voiprouter1:/usr/lib/asterisk/modules# grep PITCH *
Binary file func_pitchshift.so matches
root@voiprouter1:/usr/lib/asterisk/modules#
3. We can also find the dependencies:
root@voiprouter1:/usr/lib/asterisk/modules# ldd func_pitchshift.so
linux-gate.so.1 => (0xb776e000)
libpthread.so.0 => /lib/i386-linux-gnu/i686/cmov/libpthread.so.0 (0xb7747000)
libc.so.6 => /lib/i386-linux-gnu/i686/cmov/libc.so.6 (0xb75e4000)
/lib/ld-linux.so.2 (0xb776f000)
4. That’s it! Thanks to meral.
