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,
J.

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 failure route: if (t_check_status("401|407")) { xlog("L_INFO","failure_route(ROUTEFAIL) @@ call to uac_auth()\n"); uac_auth(); t_relay(); exit; }
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).
