This is the answer i got on the list :
The second REGISTER (the block 3) must contains the response to the
authentication challenge carried by 401 reply (block 2). That means that
the block 3 must contain an Authorization header with authentication
credentials computed according to HTTP-Digest authentication mechanism
(RFC2617).

12(21360) receive_msg: cleaning up
For some reason that i can not figure out i don't receive anything on
the radius logs.
it's looks like my granstream ATA286 not going through authectication process.
when i change the ip of the sip server to different one (2-server)
it's working perfect.
The grandstream ATA286 sending same packets, on the 2 server it's
working, on 1- one nothing happens.
on the problematic server i have clean installation of freeradius-1.02
radiusclient-4.8 ser-8.14
I tested the installation of the freeradius with the :
radclient -f digest localhost auth testing123
Received response ID 134, code 2, length = 45
Reply-Message = "Hello, test with digest"

I need some help to figure out that's the problem with this server.
And what can be a reason what i don't see any authentication process
in the radius , when the packets coming from ATA286
to authenticate the the user.
Thanks for any help.
