Re: [ATLSIP] Proxy Authentication User is empty

[tom s. <tom...@gm...>]

hello Joegen,


thank you for taking the time to reply. i am using ATLSIP in my own program but i am using it as an activeX component.


i do set the AuthenticationUser property but i can't fin  REGISTER method (i assume that is handled by the DoLogin method ?).


my question was about how i find out what the ProxyAuthenticationUser should be. where can i find this ?


when i use a sip client like x-lite i never specify what the ProxyAuthenticationUser is and it finds out by looking at the response from the server when it returns a "407 Proxy Authentication Required"


i can see in a network trace that in this "407" sip message it has a +Proxy-Authenticate: Digest realm="asterisk", nonce="453baf90"+  section that x-lite must copy to send the next INVITE..


this is all what i assume happens, please let me know if this is not the case.


so in short i would like to know where i can find what the Proxy-Authenticate should be...

thank you Joegen !


it all makes sense now and after setting the values explicit for both REGISTER and INVITE so the proxy is the same as the asterisk server the library automatically re-sends the INVITE request with the correct details after a "407 proxy authentication required" from the server..


 i am a very happy owner of a very small voip software phone now :) 


thank you again. the initial steps to a working program are always the hardest and i had some wrong assumptions in there. 


best regards,
tom

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.
