Hi Daniel,

Thanks for your reply. I dug in a bit more and found out that the sipml5 doesn't calculate the digest correctly when AKAv1MD5 or v2 is selected as default (have no idea why). So, I set the default authentication algorithm as Digest MD5 and now I can register the UE.

Cheers,
Serhat

Hello,

maybe you can get more hints about what happens there by running with debug=3 inside the kamailio cfg.

Cheers,
Daniel

Hi,

I am trying to register sipml5 webrtc client to my kamailio IMS setup. I have tried to register the client both with ws and wss, but it seems to be that the sipml5 doesn't calculate the authentication digest right. The authentication mechanism i set to AKAv1-MD5 as default in the hss. A simple wireshark file is attached. .10 being the host, .11 being the kamailio server.

From the output of scscf we can see that the digests do not match.

Thanks a lot,
