ILBC codec

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:
