The iLBC source has been removed from Asterisk due to licensing concerns
Can be installed back again using instructions from page: http://www.voip-info.org/wiki/view/iLBC
Simple instructions if above guide does not work
Go to your asterisk directory:
cd /usr/src/ASTERISKDIRECTORY
Afterwards
cd /contrib/scripts
wget -P codecs/ilbc http://www.ietf.org/rfc/rfc3951.txt
wget -q -O - http://www.ilbcfreeware.org/documentation/extract-cfile.txt | tr -d '\r' > codecs/ilbc/extract-cfile.awk cd codecs/ilbc && awk -f extract-cfile.awk rfc3951.txt
Copy all contents from
/usr/src/ASTERISKDIRECTORY/contrib/scripts/codecs/ilbc/ to /usr/src/ASTERISKDIRECTORY/codecs/ilbc/ directory
Recompile Asterisk for ilbc codec support:
cd /usr/src/ASTERISKDIRECTORY
./configure
make
Select ilbc codec for installation
make menuselect
make install
To check if codec is installed, connect to Asterisk CLI and issue command:
core show translations
You should get a similar output:
server*CLI> core show translation
Translation times between formats (in milliseconds) for one second of data

Alternative method without recompiling entire Asterisk (tested on Asterisk 1.8.14)
rm -rf /usr/src/asterisk-1.8.14.0 cd /usr/src/ tar xvfz asterisk-1.8.14.0.tar.gz cd /usr/src/asterisk-1.8.14.0 ./configure make menuconfig
Go to "Codec Translators" and make sure "codec_ilbc" is checked. Save changes and Exit (press x).
make cp /usr/src/asterisk-1.8.14.0/codecs/codec_ilbc.so /usr/lib/asterisk/modules/ asterisk -vvvr > module load codec_ilbc.so
