Secure communications, the third layer of Avaya's hardening strategy, provides numerous features and protocols to ensure secure transmissions through Avaya communication systems. Messaging and its media gateways use media encryption to ensure privacy for the voice stream. Alongside media encryption, integrated signalling security protects and authenticates messages to all connected media gateways and IP telephones and eliminates tampering with confidential call information. These features protect sensitive information like caller and called party numbers, user authorization, barrier codes, sensitive credit card numbers and other personal information which the caller enters during calls to banks or automated retailers.
Critical adjunct connections like the CTI link can be isolated to a dedicated security zone and encrypted.
