Help about TURN server

[oleg201119]

Hello
I'd like to use free TURN server.
I need only audio call between two users.
var config = {
isInitiator: isInitiator,
turn: {
host: 'turn:numb.viagenie.ca',
username: '[email protected]',
password: 'muazkh'
},
streams: {
audio: true,
video: false
}
};

I tried this configuration, but I can't hear any audio.

Looking forward to your hearing.

Thanks
