Too often, security is an overlooked aspect of an IP Telephony (IPT) deployment. While the technology offers significant business benefits, it can also open enterprises to considerable risks. This research note explores the following components of a secure IPT strategy:

- Protecting IP endpoints and call servers.
- Encrypting call signaling and media streams.
