About SipFlow – SIP & VoIP Call Flow Analyzer - DEPRECATED
*** DEPRECATED ***
We launched an improved client-side debug and analyzer at https://www.sipflow.dev. Free to use, same great features just in a universal location for non-chrome browsers and also upload PCAPs from the CLI. If you were a homer live stream user, we released a new chrome extension to bridge the call data locally and expanded to WebRTC clients.
Check out the new features at https://www.sipflow.dev
This version will stay alive, for as long as Chrome Web Store allows.
