Feature Description
Software suite of integrated
voice applications
Provides functions such as voice conferencing and manual attendant
console without special-purpose voice-processing hardware.
Enhancing its capabilities at a customer location requires upgrading
software on the server platform, thereby avoiding expensive
hardware upgrade costs.
Distributed architecture across
an IP network
Improves system availability and scalability of Cisco CallManager
servers and all Cisco IP phones, gateways, and applications.
Call admission control Ensures that voice QoS is maintained across constricted WAN links
and automatically diverts calls to alternate Public Switched
Telephone Network (PSTN) routes when WAN bandwidth is not
available.
