Features in That and Later Releases
Media and Signaling Authentication and Encryption Feature for Cisco IOS MGCP Gateways
Provides support for Cisco Secure Survivable Remote Site Telephony (SRST) and voice security features that include authentication, integrity, and encryption of voice media and related call control signaling.
MGCP-Controlled Backhaul of BRI Signaling in Conjunction with Cisco CallManager
Provides MGCP service to remote-office media gateways that connect by means of ISDN BRI trunks to a centralized Cisco CallManager media gateway controller for the purpose of call processing. This feature is supported on the Cisco 1700 series.
Adds support for the MGCP NAS package on universal gateways. Data calls can be terminated on a trunking media gateway that is serving as a NAS. Trunks on the NAS are controlled and managed by a call agent supporting MGCP for both voice and data calls. The call agent must support the MGCP NAS package.
