A2Dominion Group | Non Profit | 1000 | $556M | United Kingdom | Cisco Systems | Cisco VoIP | PBX, VoiP and Phone Systems | 2015 | n/a | In 2015, A2Dominion Group implemented Cisco VoIP to provide enterprise telephony across its organization. The deployment aligned to the PBX, VoiP and Phone Systems category and established Cisco VoIP as the primary voice platform for corporate communications and operational teams in the United Kingdom. The implementation used standard PBX and VoIP functional capabilities including centralized call routing, voicemail, handset provisioning, softphone clients, and conferencing services. Architecturally the deployment was configured as a networked IP voice environment, leveraging IP endpoints on campus LANs, voice VLAN segmentation and QoS policies to prioritize voice traffic, and centralized telephony configuration and directory services for extension management. Operational ownership sat with the IT infrastructure function, which implemented provisioning workflows, change control for telephony configurations, and capacity planning for concurrent calls. Cisco VoIP serviced corporate offices and field operations, impacting business functions such as facilities coordination, IT operations, and customer-facing communication channels, with the Infrastructure team maintaining governance over device onboarding, firmware updates, and call routing policies. | |

ACCA (Association of Chartered Certified Accountants) | Non Profit | 1341 | $298M | United Kingdom | Cisco Systems | Cisco VoIP | PBX, VoiP and Phone Systems | 2017 | n/a | In 2017, ACCA implemented Cisco VoIP as part of a Cisco integrated IP network and IP communications solution in the PBX, VoiP and Phone Systems category, to support membership and call centre operations for the organisation. The deployment targeted management of huge fluctuations in call centre traffic and reducing telephony costs by 10 percent every year while maintaining communications for approximately 350,000 members and students worldwide. The architecture consolidated data and voice onto a single Cisco IP network hosted from ACCA's main administration, data centre and global call centre in Glasgow, with unified IP telephony endpoints, session management and real time network monitoring. Functional modules and capabilities implemented included IP telephony provisioning, call routing and distribution, unified network management and the Cisco IPCC Express contact centre module providing intelligent call distribution with overflow to second tier agents. Integrations were executed across ACCA's network estate to centralise management and reporting, enabling real time visibility of voice and data traffic across single site and remote international offices and reducing inter office call costs by routing calls over the IP network. Operational coverage explicitly included membership services, the 50 strong call centre team, and administrative functions supporting 105,000 members and 245,000 students across 160 countries. Governance and process changes removed multi vendor complexity by consolidating vendor contracts and centralising support processes, which simplified incident resolution and capacity planning. The implementation of Cisco VoIP delivered a component based platform for future voice and data initiatives, ensured consistent service levels to international offices and achieved the reported annual telephony cost reduction of 10 percent. | |

Testing and procedural validation preceded site rollouts using Kaseya procedures, and device onboarding workflows were integrated with Active Directory for user account creation and permission assignment. Operational governance relied on Zendesk ticketing to manage and process support actions and requests, and IT staff monitored systems in operation to troubleshoot errors and maintain service across the 24 school sites. The Cisco VoIP deployment ran alongside wireless and endpoint initiatives involving Cisco access points and HP laptops, situating Cisco VoIP within staff communications, IT support workflows, and classroom technology operations. | |
