Hi Denis,

Use the $hdr() to extract the hdr with the nonce in combination with some transformations and regular expressions to get the value for the nonce field.

    Hi Denis,



    As OpenSIPS is the registrar, it it the one generating the nonce
    (via the www_challenge() function). At script level, you do not
    have visibility over the sent nonce .

    Hi Denis,



    Just be sure :

    1) during authentication, your proxy/registrar(s) allow to
    have cross challenging - one server is firing the auth
    challenge, but another one receives the reponse

    2) the registrations are shared between all your registrar
    servers.



    Otherwise, just give it a try and test ;)

    Hello!


    I am sorry that it was early, but i could not find an
    answer for my question.


    I want to ask for advice from community about how can i
    use Opensips as c "clean" Load_balancer for my project?

    The scheme of the project is a classic.


    Load_balancer ---> Proxy1/Register1

    | |

    | | mysql replication.

    | |

    |_____________> Proxy2/Register2


    One load_balancer, two (or more) Proxies which have
    mysql replication relationship.


    What do i mean about "clean"? I mean that it should
    ONLY act as a balancer. It should be entry point into my
    network and it should "live forever" (UPS, protected
    server, NO MySQL interaction dialing with transaction
    processing). It should not make any other action about
    call processing (besides TCP <-> UDP conversion).
    All actions (Call processing, authentication, Registration
    etc.) should "live" in Proxies.


    So, my question is, can i do it?

    Will Opensips work correctly in such scheme, including
    authentication procedure of the Call or Register
    processing?


    Thank you for any help.
