[SR-Users] dialog table entry not deleted after call if in-dialog requests are challenged

Hello,
right, I missed the headers and the spilt of the logs.
I think this is related to the 3.1.x version of dialog module which was
not designed to work with stateless replies, which is the case for
authentication challenges.
Can you update your config file for authentication so that before
proxy_challenge() you add t_newtran() and try again?
Cheers,
Daniel
