[OpenSIPS-Users] uac_auth to uac_registrant module

[Igor Olhovskiy]

Hi again.
Seems to be,  $hdr(Proxy-Authenticate) is NULL at 401 response.

failure_route[1] {
    ...
    if ( t_check_status("40[17]") ) {
    ...
    xlog("L_INFO", "Asterisk flavour $hdr(WWW-Authenticate), Proxy
flavour $hdr(Proxy-Authenticate)");
    }
}

becomes

/usr/sbin/opensips[18983]: Asterisk flavour <null>, Proxy flavour <null>

It's logic, cause in failure_route we work with initial INVITE, but not
401 reply. Cause, if we working with reply directly, we can't apply
uac_auth function to it.
