VoIP - IP Telephony White Papers
How Cisco IT Migrated to Centralized Call Processing
Overview When Cisco Systems replaced its traditional PBX systems with Cisco CallManager clusters, employees on campuses worldwide began using Cisco IP phones and Cisco IP SoftPhone software. By consolidating its separate networks for voice and data, Cisco significantly reduced its IT burden and gave employees access to productivity-enhancing IP applications. Cisco met this challenge first by dramatically reducing the number of Cisco CallManager clusters. This Centralized Call Processing (CCP) extends CallManager capabilities to remote field offices without the loss of IP telephony features. In the event of a failed WAN link, Cisco Survivable Remote Site Telephony (SRST) allows remote office workers to use their IP phones to dial out and receive calls using the Public Switched Telephone Network (PSTN).
