Yes REGISTER will be sent out upon calling DoLogin() method

ProxyAuthenticationUser is set by the application.  If you want to use 
the same credentials for both REGISTER and INVITE, you need to 
explicitly set their values as equal by calling AuthenticationUser and 
ProxyAuthenticationUser and feed them a common value.  Do the same for 
the password.  Do not forget to call InitializeSIP() after changing any 
property in ATLSIP

atlsip.AuthenticationUser = atlsip.ProxyAuthenticationUser = "myusername";
atlsip.AuthenticationPassword = atlsip.ProxyAuthenticationPassword = 
"password";
atlsip.InitializeSIP();

The server never sends the user in the challenge.   You have the wrong 
assumption here.  The only difference with x-lite is that x-lite assumes 
that the authentication credentials for the registrar and the proxy is 
always the same.  ATLSIP allows you to have separate credentials for 
registrar and proxy so you must explicitly set them both.
