The State of Delaware sought a state-wide end-to-end IP communications infrastructure, to reduce expenses and improve collaboration. The state’s Department of Technology and Information (DTI) turned to Acme Packet’s high-capacity Net-Net Enterprise Session Border Controllers to address their demanding scalability and performance requirements.
Specifically designed to overcome the interoperability, service quality and security challenges enterprises often encounter when implementing end-to-end multi-vendor IP communications networks, Acme Packet E-SBCs enable the state to enjoy all the benefits of a state-of-the-art unified communications system without compromising service integrity or availability.
As the State of Delaware’s central IT organization, the DTI is chartered to exercise governance over the technology direction and investments of the state. Supporting the IT needs of over 40,000 state employees, the department delivers core services to all state organizations including the Legislative, Executive, Judicial branches, public schools and the various agencies and quasi-agencies that serve the citizens of Delaware.
DTI is committed to delivering high quality and cost-effective services that meet or exceed user requirements. As part of that commitment, DTI implemented an end-to-end IP telephony network to improve communications and reduce equipment and operations expenses.

The State of Delaware historically procured IT services and equipment at a departmental level. Each organization was free to select the IT solutions and providers that best met their particular financial and functional objectives. This autonomous approach to procurement led to system disparities, equipment incompatibilities and cost inefficiencies. In the telecommunications realm, the state had accumulated a disjointed telephony infrastructure comprised of disparate phone systems with independent PSTN trunks, separate voicemail systems and incompatible dial plans.
The state embarked on an aggressive program to centralize decision making and consolidate IT infrastructure under Department of Technology and Information with the goal of improving employee productivity and collaboration, eliminating inefficiencies, reducing capital equipment and operations expenses. To that end, DTI set out to evolve the state’s fractured TDM-based voice infrastructure into a uniform IP telephony network capable of delivering unified communications (UC) services across the state.
Constructing a multi-vendor end-to-end IP telephony network can be a challenge. Enterprises often encounter interoperability, service quality and security issues which can encumber deployment and lead to poor customer experiences, service outages and loss of productivity. Conventional IP networking products such as firewalls, routers and gateways weren’t conceived with interactive IP communications in mind and leave networks vulnerable to security threats and VoIP quality issues.
The state sought a session border control solution to mitigate protocol interoperability and interworking issues, protect their private IP network and ensure service quality. DTI originally evaluated a Cisco Unified Border Element (CUBE) solution, but quickly determined that the CUBE could not meet the state’s high scalability requirements.
DTI decided to replace the capacity-constrained Cisco equipment with Net-Net Enterprise Session Border Controllers (E-SBCs) from Acme Packet. Known for delivering performance and reliability, Acme Packet SBCs are used by 41 of the Fortune 100 enterprises and 48 of the world’s top 50 service providers, including Verizon Business—the state’s SIP trunk service provider.
Acme Packet E-SBCs address critical IP communications security, interoperability and reliability challenges, plus provide centralized session routing and control functions which are instrumental for implementing uniform telephony services.
Key features include the following:
DTI deployed Acme Packet Net-Net E-SBCs in their Wilmington and Dover data centers. The E-SBCs’ comprehensive protocol interworking capabilities, rich session control functions and extensive SIP header manipulation features enabled the state to construct an end-to-end IP telephony infrastructure comprised of Avaya, Cisco and Microsoft solutions, with global dial plans, unified voicemail and messaging.
The E-SBCs also serve as the termination point for Verizon’s Burstable Enterprise Shared Trunking (BEST) SIP trunking service. The state installed a high availability (HA) configuration with redundant E-SBCs and interfaces to enable continued operation in the event of equipment or trunk failures.
Acme Packet E-SBCs let the state realize all the benefits of an end-to-end IP telephony network without sacrificing reliability, availability or security. State agencies enjoy lower costs and better service, and state workers enjoy the added convenience and productivity provided by the latest UC offerings.
Key benefits of the unified IP telephony network include:
The end-to-end IP communications infrastructure provides a solid foundation for the future. SIP has emerged as the protocol of choice for interactive IP communications and is supported in a wide variety of UC applications and devices. Going forward, the state plans to introduce SIP-based video and other interactive communications tools to improve collaboration and enable state agencies to better serve the citizens of Delaware.
DTI is also working with neighboring states to implement an emergency communications infrastructure as part of the Federal Highway Administration’s fiber broadband initiative. Acme Packet E-SBCs will play a key role in peering the state’s SIP infrastructure with other state networks.
