which server can work with sipML5 api

Hi all,

My question is very basic one, but troubling me from long time. I am novice 
user.
I built application like http://sipml5.org/call.htm
but some accounts wont work with it even they wont work with demo page.

I want to know:
1. which server can work with sipML5 api? where I can get list or hint of 
public sip server? which accounts will work with sipML5?
    like following wont work: 
    a. sip2.phonepower.com  -> error url too long
    b. sip.voipfone.net -> error 488 and disconnect
    c. ringio.onsip.com -> error occured 403 Forbidden

2. in my application, sip wont work if private identity is different than 
display name. it should be same, is it required?
3. my proxy server is ws://***.****.***.***  I wont accept connection from 
https, how to make it enable to do that? I tried wss"//**.***.***.** it was not 
working.
4. to solve all above do I need to work on webRTC? 

Please help me in this, I searched on internet but some solutions are working 
for one type of server and creating other problem.

Thank you so much in advance.
