Siren7 and siren14 for Asterisk

G.722.1 is the same thing as Siren7, and G.722.1 Annex C is the same thing as Siren14. These codec's are used in the newer Polycom devices that advertise HD Voice.

There are a couple of steps to installing the siren codec for Asterisk.

siren 7

The first thing you need to do is to download the benchmark binary for your platform and then execute. This will tell you which module you will need to download.

For my installation it recommended barcelona.

wget http://downloads.digium.com/pub/telephony/codec_siren7/asterisk-1.6.2.0/x86-64/codec_siren7-1.6.2.0_1.0.5-barcelona_64.tar.gz
tar xvzf codec_siren7-1.6.2.0_1.0.5-barcelona_64.tar.gz
mv codec_siren7-1.6.2.0_1.0.5-barcelona_64/codec_siren7.so /usr/lib/asterisk/modules/
rm -rf codec_siren7*
rm -f bench*

siren 14

As with siren7 you need to download the appropriate benchmark application for siren14 and then the required codec. for my installation it once again recommended the barcelona codec.

wget http://downloads.digium.com/pub/telephony/codec_siren14/asterisk-1.6.2.0/x86-64/codec_siren14-1.6.2.0_1.0.5-barcelona_64.tar.gz
tar xvzf codec_siren14-1.6.2.0_1.0.5-barcelona_64.tar.gz
mv codec_siren14-1.6.2.0_1.0.5-barcelona_64/codec_siren14.so /usr/lib/asterisk/modules/

load the new modules

To load the new modules into Asterisk you can either restart or
