Default Learn about VoIP security concerns.

For those who are a bit concerned about VOIP security, I would strongly recommend Practical VoIP Security written by Thomas Porter, Jan Kanclirz Jr.

You will learn fully about the impact on your VoIP network of PSTN, SIP, H.323, firewalls, NAT and encryption.

An excellent book with over 500 pages.
