Hello,
I am working with the latest version of sipp 3.1 available under sourceforge
that I colmpiled under cygwin ( with pcap and ossl support )
I am trying to set up a REGISTER scenario with MD5 authentication. My problem
is that when I receive the 401 from the core network, sipp resend a message
with the field cnonce=0
I ve seen that it was a problem that you encountered some time ago. I tried
several version of sipp but I never get rid of the problem.
That would really be appreciated if you could provide me some help on this
subject. I am probably doing something wrong with sipp since I am getting
started with it but I can't see what is the problem
Thanks in advance for your help
BR
François Net
