The clients manage to authenticate successfully from
remote subnets or from our local subnet but NOT while connected to our openvpn server, so
it is not an authentication issue.
The clients aren't responding to the authentication challenge. How OpenVPN is
contributing to that I can't say. Are the clients actually seeing the responses from
Kamailio?

Thank you for your help
The REGISTER request is getting to kamailio.
I attach my tcpdump output:

Your client is never responding to the authentication challenge returned by Kamailio in
the WWW-Authenticate header. Your client should be attempting a second REGISTER with an
Authorization header containing a response to Kamailio's challenge. Do the clients
have authentication enabled?

what do you mean by "register fails"?
Is the REGISTER request getting to kamailio? Is there a reply for it?
A ngrep output taken on kamailio server for such registration would help to figure out
where is the issue.
Cheers,
Daniel
