New subject: sipml5 register to kamailio IMS (Unauthorized - Challenging the UE)

14 Oct 2016

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.
