How to install silk codec

I’m troubleshooting on how to install the silk8, silk12, silk16, silk2 codecs… My processor of my PIAF asterisk sever (amazon ec2) is Intel® Xeon® CPU E5-2650 0 @ 2.00GHz. I tried downloading the .so file from digium.com and I added to the modules directory in my sever but it didn’t work. Then I added this line of code
[silk8]
type=silk
samprate=8000
fec=true
packetloss_percentage=10
maxbitrate=20000
dtx=false

[silk12]
type=silk
samprate=12000
fec=true
packetloss_percentage=10
maxbitrate=25000
dtx=false

[silk16]
type=silk
samprate=16000
fec=true
packetloss_percentage=10
maxbitrate=30000
dtx=false

[silk24]
type=silk
samprate=24000
fec=true
packetloss_percentage=10
maxbitrate=40000
dtx=false

To /etc/asterisk/codecs.conf but that failed too… :frowning:
