Hello All, By the way, it could be that I don't understand something about the registration/authentication concept implemented in sofia-sip. Given this scenario where the username or password is incorrect, then as the phone periodically retries registration, a user must EITHER correct the username/password in the phone OR correct the username/password in the server.
Is sofia-sip smart enough to know that if the username/password is changed at either endpoint, then it will then add the authentication header to the REGISTER message (in reply to the 401)?

However, Mikhail's suggestion of commenting out the auc_clear_credentials() call in nua_base_client_check_restart() function works. Now subsequent nua_register() calls include the authentication header in the 401 reply. Perhaps I should explain my implementation: I first call nua_register() from my app. When 401 is received, I call nua_authenticate(). If the username/password is bad, my app receives the 904 No matching challenge upon receipt of the 2nd 401 reply. Then I wait 30 seconds and start the process again. Do you know any pitfalls I might encounter if I leave the auc_clear_credentials() call commented out?

Ehm, it wasn't strictly a patch, I was just experimenting. I did it against an older tree. There have been code movements in nua recently, so I dropped it for a clean update. I will try to redo it and check when I have more time. Look for a comment like "Bad username/password pair" in the nua code. Pekka may know better where the line is now.
