Security

Configurable operation modes—Nonsecure or secure.

Device authentication—New model phones have an embedded X.509v3.

Certificate; a certificate authority proxy function (CAPF) is used to install a locally significant certificate in phones.

Data integrity—TLS cipher “NULL-SHA” supported; messages are appended with SHA1 hash of the message to ensure that the

message is not altered on the wire and can be trusted.

HTTPS support for the following applications—Cisco Unified CallManager Admin, Cisco Unified CallManager Serviceability,

Cisco Unified CallManager User, RTMT, Cisco Unified CallManager TraceAnalysis, Cisco Unified CallManager Service, the

Cisco Unified CallManager Trace Collection tool, and the Cisco Unified CallManager CAR tool all have HTTPS support.

Privacy—Cisco Unified CallManager supports encryption of signaling and media. Phone types include Cisco Unified IP Phone

7940G, 7941G, 7941G-GE, 7960G, 7961G, 7961G-GE, 7970G and 7971G; Survivable Remote Site Telephony (SRST) and

MGCP gateways are supported.

Secure Sockets Layer (SSL) for directory—Supported applications include BAT, CAR, Cisco Unified CallManager Admin User

Pages, Cisco Unified CallManager Assistant Admin Pages, Cisco Unified CallManager User Pages and IP Phone Options Pages,

Cisco Conference Connection, CTI Manager, Extension Mobility, Cisco Unified CallManager Assistant, and Multilevel

Administration (MLA).

A USB eToken containing a Cisco rooted X.509v3 certificate is used to generate a Certificate Trust List (CTL) file for the

phones as well as configuring the security mode of the cluster.
