DescriptionFeature
When connected to Cisco Unified Communications Manager Release 10.5(2) and later, the
phones support AES 256 encryption support for TLS and SIP for signaling and media
encryption. This enables phones to initiate and support TLS 1.2 connections using AES-256
based ciphers that conform to SHA-2 (Secure Hash Algorithm) standards and are Federal
Information Processing Standards (FIPS) compliant. The new ciphers are:
•
For TLS connections:
â—¦
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
â—¦
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
•
For sRTP:
â—¦
AEAD_AES_256_GCM
â—¦
AEAD_AES_128_GCM
