Due to low download volume and subsequent declining revenue, I've decided to take phase this web site out.
SIPFlow has now been moved to an open source project on SourceForge. Please visit
https://sourceforge.net/projects/sipflow/ to learn more about
how you can download and run SIPFlow. If you have the time and skill, I'd love to have you help with maintaining (or improving)
the source code as well!
Thanks for all everyone's support over the years. Developing SIPFlow was a wonderful experience.
