IP Telephone Technical Details

Enterprise IP Telephony is built on an Avaya Communications Manager system with its control infrastructure located within the N.C. Department of Information Technology's data centers. The Avaya CM runs on a series of servers and gateways that enables voice applications to run on the agency customer's local area network infrastructure. These devices provide open platform computing and centralized call telephony processing that is distributed across a multi-protocol IP network including asynchronous transfer mode and metro ethernet services to support a highly diversified and highly available network architecture. The platform can support a variety of agency network configurations, such as campus, multi-site, branch (networked or distributed), remote, small and home offices.

The CM software is Avaya's latest generation of voice application software, providing users all the features and functionality of a traditional telephone system as well as many new features, all on an IP network. EIPT provides rich capabilities for users upgrading from traditional circuit-switched networks as well as for new IP deployments and will run on most customer agencies' quality of service-capable LAN networks.

A typical customer location is set up as a remote gateway connected via the state wide area network to the state's geographically distant data centers. Our servers and gateways provide call setup, voicemail services, long-distance calling facilities and toll-free calling facilities. Each customer site has backup calling capability in the event the site's WAN access to us is lost.
