Hello,

Please verify there is no WCS process running:
Code: 
ps aux | grep flashphoner
If there is such process, kill it and then try to start WCS.

If startup fails, try to start with stdout output to see the errors.

We can check the server if you send the access details using this form.

please note that with the following command the service is starting but showing the status as failed...

but with systemctl start webcallserver command it is not starting:

[root@xms bin]# ./webcallserver start

[root@xms bin]# sudo systemctl status webcallserver

Credentials sent via form, please let us know what is the issue as we have to apply this to a production site, the earlier wcs version was having voice issue in video chat application when used with Edge browser, we will check it with this new version if the problem still persist.

We checked the server. Seems like you have a bug in systemd. We changed the user to start webcallserver.sevice to root with the command
Code: 
/usr/local/FlashphonerWebCallServer/bin/webcallserver fix-service
and commented the capabilities line in /etc/systemd/system/webcallserver.service:
Code: 
[Service]
SuccessExitStatus=143

User=root
Group=root
LimitNOFILE=20000
# The following should be commented
#AmbientCapabilities=CAP_NET_BIND_SERVICE

Type=simple
...
Another option is to update systemd.
WCS starts and works succesfully now.

We tested Video Chat in MS Edge 98.0.1108.62, and seem like the problem is not reproducing: audio plays smoothly and in sync with video if no packet loss between server and client.

Thank you for your support, Please note that the earlier version of WCS server was running OK with systemd so I am not sure what went wrong...

Additionally we have noticed that still the EDGE browser from different android mobiles are facing voice related issue when using video chat demo, kindly assist how can we fix that?

Reproduced this issue with Edge on Android: if the participant using Edge joins first, then when another participant joins that participant's video freezes when appears in Edge, or starts playing without audio (ticket WCS-3445 submitted). In Conference demo, there are Stop | Play buttons for players, and if stop and resume playback when a new participant joins, his video plays with audio.
Please let know if that is the behavior you encountered.

In WebSDK build 2.0.216, it is possible to pass participant stream playback options. Use this to disable automatic stream audio unmuting in Android Edge browser and to prevent a participant stream freeze. Then, user must click a button to unmute audio
Code: 
var options = {
    unmutePlayOnStart: true,
    constraints: {
        audio: {
            deviceId: 'default'
        }
    }
};
// Leave participant stream muted in Android Edge browser #WCS-3445
if (Browser.isChromiumEdge() && Browser.isAndroid()) {
    options.unmutePlayOnStart = false;
}
participant.getStreams()[0].play(display, options).on(STREAM_STATUS.PLAYING, function (playingStream) {
    ...
    // Set up participant audio toggle button #WCS-3445
    if (audioBtn) {
        $(audioBtn).text("Audio").off('click').click(function() {
            if (playingStream.isRemoteAudioMuted()) {
                playingStream.unmuteRemoteAudio();
            } else {
                playingStream.muteRemoteAudio();
            }
        }).prop('disabled', false);
    }
    ...
}};
