I followed this link https://www.webrtc-experiment.com/docs/TURN-server-installation-guide.html#centos to install turn server in centos 7. The Configuration step I gave user name and password , also gave the same port as per the guidelines.
And finally I run the comment:
"turnserver -v -r 127.1.1:2222 -a -b turnuserdb.conf -c turnserver.conf -u turn-username -r 127.1.1:2222 -p turn-password"
it showed Wrong user name in the execution.
Any idea for Coturn installation in Centos7 because i am new in webrtc...
