Media authentication and encryption on Cisco integrated services routers, together with media encryption on Cisco Unified IP phones and Cisco Unified Communications Manager, provides a highly secure environment for IP communications across a WAN or LAN. As illustrated in Figure 1, SRTP is used to encrypt voice calls placed on voice gateway network modules in branch office A. This provides secure calls from analog phone to analog phone, or fax machine to fax machine, within the office. Similarly, secure calls are enabled from time-division multiplexing (TDM) endpoints or analog phones at branch office A to Cisco Unified IP phones at the headquarters. The signaling between the gateway at branch office A and Cisco Unified Communications Manager is secured using IPSec, and the signaling between the IP phones at headquarters and Cisco Unified Communications Manager is secured using TLS.

Key Features and Benefits


Media Authentication and Encryption


Media encryption currently delivers end-to-end encryption for voice calls between Cisco Unified IP phones. The introduction of media encryption on Cisco routers adds the ability to place secure IP phone-to-gateway and gateway-to-gateway calls. Callers can now place encrypted calls to the PSTN gateway using IETF RFC3711 standards-based SRTP. SRTP encrypts only the payload of a voice packet without adding additional encryption headers. Because of this, an SRTP-encrypted voice packet is almost indistinguishable from an RTP voice packet, allowing features like quality of service (QoS) and compressed RTP to be supported without any additional development or packet manipulation. In addition, SRTP uses the largest practical key size supported by the AES encryption standard for increased security. Voice encryption keys are generated for each call, ensuring a higher level of security protection. Media authentication also validates the identity of the devices encrypting the calls.
Media encryption using SRTP is suitable for voice privacy and confidentiality on the LAN to protect against internal threats. In addition, media encryption can also be delivered across an IP WAN or the Internet, using the same VPN infrastructure deployed for data.

Signaling Authentication and Encryption


Signaling authentication and encryption between the gateways/CUBE and Cisco Unified Communications Manager is protected using IPSec. This ensures that signaling information such as dual tone multifrequency (DTMF) digits, passwords, PINs, and voice encryption keys are secure. Both software-based IPSec, available in Cisco IOS Software, and hardware-based IPSec using the AIM-VPN modules are supported.

Scalability of Encrypted Calls


SRTP media encryption is performed on DSP modules and not on the router CPU. This enables efficient scalability as increasing the number of voice gateway interfaces with DSPs, or increasing the number of DSPs integrated on the platforms (such as on the integrated services routers), increases the number of DSPs available for secure calls.
