@estel, ok, I am convinced... I am ditching skype and have signed up with a SIP provider... getonsip.com

Ok, I have an account & signed on via my PC web browser..
Can Estel advise how to sign on via my N900?

I have gone into VoIP and IM accounts. Created an entry under SIP, put in my user id:-
My SIP address {Your SIP address: my_name@getonsip.com}
and
password.

But this does not log on... Reports 'Username or password incorrect'
I notice the 'Advanced Settings' but don't know what to do with them. I suppose that there has to be a domain setting entered somewhere, also probably a port etc...
Also put user_name in advanced settings... 'my_name'
Help would be apreciated now that I have been turned.
