Noise or metalic sound with codec_g723 Configure /etc/asterisk/codecs.conf [g723] sendrate=63 or 53 as described at the top of this page.
Distorted sound Disable VAD and CNG in phone and/or your VOIP provider.
show translation - codec is not loaded Bump asterisk verbosity level with -vv and watch for messages right after 'loading module codec_g729...'
loader.c... /usr/lib/asterisk/modules/codec_g72...: cannot restore segment prot after reloc: Permission denied Execute: $ chcon -t textrel_shlib_t /usr/lib/asterisk/modules/codec_g72[39]*.so This happens when SELinux is enabled and Asterisk process cannot load the codec because of ELF TEXTREL in shared library. This is how IPP works and that is fine.
Error loading module codec_g72...: cannot open shared object file: No such file or directory Check $ ldd codec_g729.so $ strace -o trace.log -efile -f asterisk send ldd output and trace.log file to Asterisk G.729 Google group.
Error loading module codec_g72...: wrong ELF class: ELFCLASS32 Use x86_64 binaries because you're running 64-bit OS.
$ ldd codec_g729.so: not a dynamic executable You are running 32-bit, see Notes - note #2
Asterisk crashing at startup If Pentium4 codec is not working, try -no-sse builds, try Pentium3. Try ICC builds. Doesn't work - try Pentium and Debug builds.
Asterisk still crashing at startup Compile asterisk with CFLAGS=-g Run asterisk in gdb (with original and -debug version of the codec): $ gdb /usr/sbin/asterisk (gdb) r -cvvv when it crashes do: (gdb) set disassembly-flavor intel (32-bit gdb 6.x) disassemble $eip $eip+20 (32-bit gdb 7.x) disassemble $eip, $eip+20 (64-bit gdb 6.x) disassemble $rip $rip+20 (64-bit gdb 7.x) disassemble $rip, $rip+20 (gdb) info registers (gdb) info threads (gdb) bt (gdb) l (gdb) q Send an output to Asterisk G.729 Google group together with the result of 'cat /proc/cpuinfo'.
