Thanks - I've done some progress - I've hard coded temporarily the user, pass & realm, and authentication goes out now.

However, the provider is answering with a 401 & a new nonce.

here is what I have 

INVITE --->
<---- 401 (with nonce)
ACK --->
INVITE ---> with correct nonce & response, I've recalculated the response, it is ok
<--- 401 (with new nonce)
ACK -->

When I configure another box with a plain asterisk and same credentials, the call goes through fine - so it is not because my ip is wrong or not whitelisted. 

Why would the remote send me a 401 ??? I've tried to contact them but no answer

Unlike when calling uac_reg_request_to, you'll have to fill the
auth_*_avp pvs yourself. So in the example you have to fill $avp(auser)
and $avp(apass).

modparam("uac","auth_username_avp","$avp(auser)")
modparam("uac","auth_password_avp","$avp(apass)")
modparam("uac","auth_realm_avp","$avp(arealm)")

...

if(t_check_status("401|407")) {
        $avp(auser) = "test";
        $avp(apass) = "test";
        uac_auth();
        t_relay();
        exit;
}

So next problem is how to get those credentials. You already know the
user making the call. So either have a custom query to a custom table
(sqlops/avpops) to retrieve the external user/pass for current user, or
try to store that information with the subscriber data (saw some
suggestions for this a while back on the list).
