In 2019 CGI UK implemented Mitel MiVoice Business under the PBX, VoiP and Phone Systems category as part of a multi-site telecommunications and network upgrade program across Glasgow. The implementation was executed alongside a broader municipal connectivity expansion that targeted corporate and educational sites and the rollout of tens of thousands of end-user devices to classrooms and public facilities.
The Mitel MiVoice Business deployment was delivered on an HP Aruba switching topology, with custom switch configuration files created to embed site VLANs and IP addressing schemes. Workstreams included WAN, LAN and Wi-Fi migrations, cabinet remediation and port rationalization, and the configuration, testing and cutover of Mitel IPT telephony services from an existing Cisco IPT to Mitel MiVoice Business for voice control, SIP trunking and handset provisioning.
Integrations and operational hygiene were emphasized, with detailed Visio network diagrams produced for ingestion into SolarWinds, use of SCCM for Windows 10 and application deployment, and coordination with Cityfibre and Commsworld to extend FTTP connectivity to 506 council sites. The programme also interfaced with NHS Greater Glasgow and Clyde for digital health and social care access, and included Wi-Fi coverage assessments to support the simultaneous rollout of over 50,000 iPads to schools, libraries and nurseries.
Governance relied on due diligence reporting prior to each migration, site-level testing and implementation documentation tracking old and new assets, and post-deployment floor-walking to validate service levels. Operational responsibilities spanned network transition teams and IT and business consulting services, with standardization of switch templates, documented site testing procedures and controlled cutover plans to support ongoing telephony operations under Mitel MiVoice Business.
