Hey there!
Nothing to do with the problem but I just wanted to say that you can
simplify/strengthen
the code for building the auth string by doing it like this code:
"sip" is of type <sip_t const* sip>, which is delivered by NUA to the
callback:
sip_www_authenticate_t const* www_auth = sip->sip_www_authenticate;
char const* scheme = www_auth->au_scheme;
const char* realm = msg_params_find( www_auth->au_params, "realm=" );
char auth_str[ 8192 ] = { 0 };
snprintf( auth_str, 8192, "%s:%s:%s:%s",
scheme, realm,
"USERNAME",
"PASSWORD" );
nua_authenticate( nh, NUTAG_AUTH( auth_str ), TAG_END() );
Hope it helps :-)
Regards,
Andreas
