Using the internet for your business phone (VOIP/Internet phone service) is like sending information over the world wide web….everybody can collect it. Secure your business internet phone calls with this free application called Zfone.
Zfone is a new secure VoIP phone software product which lets you make secure encrypted phone calls over the Internet. Zfone is not itself a VoIP client, but lets you make secure calls with your existing VoIP client, by filtering, encrypting and decrypting all your VoIP media packets as they pass in and out of your computer. Zfone is known to be compatible with the following VoIP clients: X-Lite Gizmo (audio, no video yet) XMeeting Google Talk VoIP client (but only when Google Talk is using RTP) Yahoo. Zfone is compatible with all SIP/RTP-based VoIP clients.
VoIP developers may use the Zfone lib ZRTP Software Development Kit to add Zfone’s ZRTP protocol to their VoIP applications. Developers may use the Zfone lib ZRTP SDK and reduce their time-to-market quite a bit. 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. For this reason, it is important that you get your VoIP client tested and working before you install Zfone. First, you will need to get yourself a VoIP client, install it, sign up for a VoIP service provider, get a VoIP phone number (a SIP URI), and test your VoIP client to make sure it all works. Many VoIP service providers provide an echo server to make a test call, and it will echo your voice back to you.
Internet based phone calls have gotten much better in quality in the last decade. It’s as if Zfone were a “bump on the wire”, sitting between the VoIP client and the Internet. I’ve just released Zfone, a new product that takes a new approach to make a secure telephone for the Internet. It was created by Phil Zimmermann, the person who solved the encryption problem for email and file transfer with Pretty Good Privacy (PGP),the most commonly used email encryption package on the Internet. Zfone works on top of existing SIP- and RTP-programs, like Gizmo and SIP phone Zfone is software for secure voice communication over the Internet (VoIP).
Windows users should not interrupt the installation process, despite multiple warnings stating that the ZRTP Miniport driver is not Windows Logo certified. It’s dangerous to interrupt the installation of any device driver on Windows, including this one. Before starting the installation process, Zfone for Windows creates the restore point, which stores your system information at the moment of installation. We expect it to work with Windows CE and Symbian mobile platforms in the near future.
Zfone is a standalone cryptographic package designed to work with VoIP communications software. Zfone is developed by the same man who brought us Pretty Good Privacy (PGP). Zfone is simply an implementation of ZTRP which is an extension of SRTP. Zfone is in no way a Skype challenger. Zfone is not a soft phone client in itself, but rather a sort of add-on that you can use together with your existing VoIP service for better privacy. Zfone is designed to work with VoIP clients that use the industry standard SIP protocol, and has been tested with clients such as X-lite, Free World Dialup and Gizmo Project. Zfone is very user-friendly since it hides most of the encryption mechanism from its users.
