The funny thing is: the subsequent 407 challenge (in a new SIPp instance, to an INVITE request) is handled deterministic without any spikes. br Michael > > Josh > > -----Original Message----- From: Michael Hirschbichler > [mailto:s...@hirschbichler.biz] Sent: Wednesday, 6 February 2013 9:06 > AM To: sipp-users Cc: sipp-devel Subject: Re: [Sipp-users] SIPp 3.3 > > Hi Rob, > > fine job - from my point of view, 3.3b2 works fine.
