kamailio sending qop in auth header - sr-users

15 Nov 2013

It may be my lack of understanding, but I moved from using auth_check function to
www_authenticate function and now see kamailio sending qop in auth header. It's my
understanding this is not necessary (based on UA types in use) so I would like to remove
it. Per module doc, it is "" by default, I tried adding auth param as below but
made no difference. What could be causing this?
