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
