ANNOUNCEMENT: PGPfone Beta 7 Now Available for Download
Sorry if this has been discussed before (please point me in the right direction if that is the case), but VSNL, my government-owned ISP (which also has a monopoly on all international traffic) made me sign that I will not use my Internet connection for voice traffic. Is there any way they could find out if I were using PGPfone, or rather, could I prevent them from finding out?
Arun: I can't give you a definitive answer here, but I'll take a shot. Most Internet telephony systems use UDP packets to transfer speech, since the lower overhead of UDP (as opposed to TCP) allows for better throughput. I assume (but I'm not certain) that PGPfone works the same way. Unfortunately, most of your other TCP/IP communication will be based on TCP packets. Therefore, it's theoretically possible for your ISP to monitor your traffic, watching for large numbers of UDP packets. --------------- Harry Hochheiser harry@tigger.jvnc.net 08 3A B5 F6 47 7F C7 C4 28 B4 8D D2 2E DF F6 1E
