[Linphone-developers] Want to modify Linphone core to use double authentication

[Julian Nicolas]

Hello linphone developers,

My name is Julian, I´ve been messing 
up with linphone for android in the last couple of months and I would 
like to add a nice modification. Right now you can only use linphone for
 SIP account that use the username as authentication username, so for 
example for the account "sip:address@hidden" linphone assumes that the username for authentication is "mysipaccount".

Now Imagine that you have a SIP account which is "sip:address@hidden"
 and imagine that in my authentication server for the account microweb10
 I want to have a different username for authentication and I don´t want
 to use the word "Julian".

So to start we need now an identificator more to set up the sip account. For the account sip:address@hidden before we had:
Usename: Julian (for authentication we will use "Julian" as username)

Password: 1234
Domain: microweb10.com
Proxy: microweb10.com

Now we will have:
Public Username: Julian
Private Username: Jul5487
Password: 1234
Domain: microweb10.com
Proxy: microweb10.com

As you can see, the sip uri should be the same for both = "sip:address@hidden",
 but before we were using "Julian" as username and "1234" as password 
for authentication. And now we need to use "Jul5487" as username and 
"1234" as password.

I did some modifications in the android code but I think I have to 
modify the core (submodules/linphone/coreapi) and I don´t know if I will
 have to modify also exosip. That´s the thing. I would like to do
 a good work. And of course if my development is usefull for linphone 
developers I will share it. But I am not really especialist in linphone 
and I have no idea on how would be the best way to do it. Which modules I
 have to mofidy. What´s the best way to do it. Which files are in play 
with this modification. Any help will be very appreciated.

Thanks in advance. Sorry about my english, and if I missed something, please let me know.

Have a good day.
