[VOIPSEC] I am a freshman in this forum:)

[Eliot Liu]

Hello, everyone! I am a graduate student in China. And I am very
interested in SIP-based VoIP System. I know that there are many
threats in VoIP, and some of the threats are difficult to tackle.

These days, my boss told me to use the PKI to help improve the security
of the SIP-based VoIP System. I found some paper from the Internet,
and read them. However, I am confused very much. Could someone here
give me some advice?

Thanks!

Bill
