Hello, In my webrtc project I not getting audio for all inbound calls, some of 
them don't get audio. Because the event iceConnectionState= connected never 
arrives.

I'm using the asterisk 13.20 and the kamailio 4.4.6 version.

For signaling I have a server with a REST API to exchange the sip messages.
In the javascript I using this webrtc-adapter 
https://www.npmjs.com/package/webrtc-adapter

Can anyone help me with this problema, Than you.

The flow in my javascript when I start the application and receive a call is 
the following:
        1 - Execute GetUserMedia and save the stream received.
        2 - Add the eventHandlers to the peerconnection
        2 - Receive an offer (call), get the tracks from the localstream, and 
execute the addTrak of the peeConnection, to add the traks and the local stream 
to the peerConnection
        3 - The user click a button to answer the call
        4 - set remoteDescription of the received offer
        5 - Create an answer without RTCOfferOptions
        6 - setLocaldescription
        7 - wait (using promises) until receive at least 2 candidates of the 
type srflx or until the Ice gathering is complete
        8 - When the Promise is resolved, an answer to the offer is sent to 
asterisk. The offer contains the sdp with the candidates 
(peerConnection.LocalDescription.sdp).
        9 - After the answer been sent, I execute the play to the audio 
htmlElement. This element will have the property srcObject with the remote 
stream received in the event ontrack.
        
My configfuration of the peerConnection is the following:

var pcConfig: any = {
                'iceServers':
                [{urls: [
                    "stun:stun4.l.google.com:19302"
                    ]}],
                'rtcpMuxPolicy': 'negotiate'
            }
                        
Using my app I get the following log from the firefox (about:webrtc):
