Good day, I was thinking of routing a VoIP call (SIP protocol) via. a VoIP client into Phillip Zimmermann's new "Zfone" ( http://www.philzimmermann.com/EN/zfone/index.html )and then into Tor before the VoIP call reaches the other party(s).
One problem I see is that most VoIP clients use UDP (I think) and so does Zfone. But, Zfone has a proxy configuration window (I think) which may route into TCP/IP. I only have a windows box and the Windows Zfone isn't released yet. I was thinking of routing a VoIP call via. a VoIP clinet into Zfone (port 5060) then into Tor (via. Torcap with Zfone). Does Torcap do UDP to TCP/IP? Another idea is to communicate with other parties via. Tor's Hidden Services(HS). Can HS be configured to route a VoIP call? Could a HS .onion address is used inplace of the other parties VoIP number in a VoIP clinet? Does anyone know of a good, open-source and free VoIP clinet for Windows XP/NT? -Slighlty off topic- What the Tor community really needs is a "UDP to TCP/IP" library for Tor (if that's even possible). This way UDP protocol specific programs could be used with Tor. I know "TCP/IP to UDP" library is possbile as UDP is the underlying protocol for TCP/IP (I think). -Back to topic- Zfone runs in the IP stack and detects a VoIP call when it starts. Zfone then captures, secures (eg. authenticates) and encrypts all VoIP packets 'on the fly'. Zfone creates an end-to-end tunnel to other Zfone users via. TLS and it also uses DH key agrements. Zfone also offers defense from MiTH attacks via. a short authentication code that appears in all parties Zfone GUI to be read over the phone for verification. Any opinions, thoughts? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
