Getting Started with Zfone. What is Zfone?
<<<... anything else that we should know. The most important thing to include-- the zfone-bug-report log file produced by the "Create bug report" command in the Zfone Help menu. We really need to see the log files from both parties, so please create and send bug reports from both sides of the conversation. For the free public beta of Zfone, bug reports are encouraged, but requests for support will likely get no response. If you want support, you'll have to wait for the official release and pay for it. Things you should know before you report bugs A word about how Zfone uses this protocol
The ZRTP protocol used by Zfone will soon be integrated into many standalone secure VoIP clients, and that is the most effective way to use the protocol. But the Zfone application is not itself a VoIP client, and uses the ZRTP protocol differently. Zfone lets you turn your existing VoIP client into a secure phone, by passing the VoIP packets through a separate encryption filter outside of the VoIP client. The Zfone software runs in the Internet protocol stack on any Windows XP, Mac OS X, or Linux PC, and intercepts and filters all the VoIP packets as they go in and out of the machine, and secures the call on the fly. You can use a variety of different software VoIP clients to make a VoIP call. The Zfone software detects when the call starts, and initiates a cryptographic key agreement between the two parties, and then proceeds to encrypt and decrypt the voice packets. It has its own little separate GUI, telling the user if the call is secure. It's as if Zfone were a "bump on the wire", sitting between the VoIP client and the Internet. Think of it as a bump in the protocol stack. We're explaining this packet fitering aspect of Zfone here because some bugs may be related to it. Don't blame Zfone for your VoIP client problems
Many things can go wrong with VoIP client software. There could be problems with your firewall, with getting VoIP calls to traverse your local network's NAT router, with your audio configuration choices (especially your microphone), with your VoIP service provider... more>>>
