It's the following snapshot: sipp.2007-01-16.tar.gz

[EMAIL PROTECTED] bin]# ../SIPp/sipp.2007-01-16/sipp -v

 SIPp v1.1, version 20061124, built Jan 18 2007, 17:13:01.


We did have a short look at the (relevant) source code, but couldn't
really pinpoint a problem.  There are however some conversions between
double and long which seemed a little odd to us, but I'm not sure if
that's related to this problem.


Kind Regards,
Bruno
