ABSTRACT
The article discusses the Chicago Public Schools system's adoption of IP-telephony technology. The city of Chicago expects to save $6 million a year as it moves from Centrex to premises-based IP-telephony services, which are cheaper to maintain and require much fewer service costs. The school district utilizes a hub-and-spoke structure for their IP-telephony network, with 75 hub sites serving an average of eight schools per hub, with each linked to the Public Switched Telephone Network with a pair of PRIs, as a backup for loss of service.
