I have just installed the Mizu WebRTC-SIP gateway on my computer. However, I am not able to use the functions as I cannot login and connect to the sip server. What should I enter in the login window to proceed to the next step? My goal is to make the Mizu Webphone connect with my sip server with webRTC, and the sip server currently does not support webRTC. 

What I have inputted are:

Server: LAN IP of sip server

Instance: mserver            Node: Empty

Username: phone extension username

Password: phone extension password

The error message is:

Reason: TCP Provider: Timeout error [258].

(ip of sip server,80:sip username)
