Please help to resolve it.

What is it?
Is it webrtc's log?

Yes its webRtc log.

Do you know what happened?

Am new to it, am not able to locate exact issue.

Are you using any WebSocket gateway?
Is "192.168.1.8" the SIP Server's IP address?

Yes am using WebSocket gateway..

And 192.168.1.8 is the brekeke SIP server I.P running on windows7 machine.

Capture packets with Wireshark at 192.168.1.8 to see whether the REGISTER packet reaches the Brekeke SIP Server.

Otherwise, check the WebSocket gateway's log.
