Authentication and
Encryption Features

• Media encryption of voice RTP streams using SRTP

• Exchange of RTP Control Protocol (RTCP) information using secure RTCP

• SRTP to RTP fallback for calls between secure and insecure endpoints

• Secure calls supported in Cisco Unified Survivable Remote Site Telephony (SRST) mode during WAN failover

• Compressed RTP (CRTP) supported with media encrypted calls using SRTP

Authentication and
Encryption Algorithm

• Supports AES-128 encryption algorithm

• Supports the HMAC secure hash authentication algorithm (SHA 1)

Signaling Authentication and Encryption Features

• Gateway to Cisco Unified Communications Manager signaling and encryption uses IPSec for Media Gateway Control Protocol (MGCP), H.323 and SIP gateways

• IP phone to Cisco Unified Survivable Remote Site Telephony router signaling and encryption uses TLS 
 (Transport Layer Security)

Protocol Support

• MGCP 0.1 (supports MGCP gateways with Cisco Unified Communications Manager)

• H.323 (supported on H.323 gateways and CUBE; Cisco Unified Communications Manager interoperability is optional)

• Session Initiation Protocol (SIP)

• SCCP (Cisco Unified IP Phone) in SRST mode

Module Support

• Any module that has PVDM2, PVDM3 and/or built-in DSP

Codec Support
