Ok - found it !!
I've managed to get the cseq incremented following the info in this post:
https://github.com/kamailio/kamailio/issues/679
Many thanks for your help,

Hi
Still searching on that one. My guess now is that I am receiving another
401 because the CSEQ does not get incremented.
INVITE cseq 102--->
<---- 401 (with nonce) cseq 102
ACK cseq 102 --->
INVITE ---> with correct nonce & response, I've recalculated the response,
it is ok -- cseq 102
<--- 401 (with new nonce) cseq 102
ACK -->cseq 102
I think the 2nd exchange should have a cseq of 103 or higher.
How can I increase it ?

// Here is the section generating the reply with the wrong cseq
if(t_check_status("401|407")) {
$avp(auser) = "test";
$avp(apass) = "test";
uac_auth();
t_relay();
exit;
}

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

I've inserted the following block on the

xlog("L_INFO","failure_route(ROUTEFAIL) @@ call to

uac_auth();
t_relay();

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).
