2.5 Unsuccessful Registration

Description:

Bob sends a SIP REGISTER request to the SIP Server.  The SIP server provides a challenge to Bob.  Bob enters her/his user ID and password.  Bob’s SIP client encrypts the user information according to the challenge issued by the SIP server and sends the response to the SIP server.  The SIP server attempts to validate the user’s credentials, but they are not valid (the user’s password does not match the password established for the user’s account). The server returns a response (401 Unauthorized) to Bob’s SIP client.

Popis:

Bob zasiela sipovú požiadavku REGISTER na SIP server. Server odpovie na požiadavku REGISTER správou 401 Unauthorized. Následne užívateľ Bob zadá svoje užívateľské meno a heslo. Tieto bobov klient zašle zašifrované serveru. Server overí správnosť informácie a v prípade že informácie nie sú shodné s tými ktoré má pridelené bob na svojom konte server zasiela opäť odpoveď 401 Unauthorized.
