 describes key features of Cisco CallManager.

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.
