Connected Businesses Perform Better
Whether you are setting up a new office, relocating, or upgrading an ageing telephony system, Constructive IT provides a complete connectivity audit and solution design. We work with leading carriers and technology partners to deliver the right mix of voice and data services for your business needs and budget.
Our engineers handle everything from initial site survey and circuit provisioning through to installation, configuration, and ongoing support — so you can stay focused on running your business rather than managing your communications infrastructure.
Our Telephony & Connectivity Services
Business Telephony Solutions
From traditional PBX systems to modern VoIP and hosted telephony platforms, we design and deploy telephone systems tailored to the scale and requirements of your organisation, ensuring clear, reliable communication across all sites.
Leased Line & Dedicated Connectivity
Achieve consistent upload and download speeds with a leased line connection. We source, provision, and manage dedicated circuits that deliver symmetrical bandwidth and guaranteed SLAs — ideal for data-intensive workloads and latency-sensitive applications.
Broadband & Fibre Connectivity
We assess your bandwidth requirements and supply the most appropriate broadband or full-fibre solution for your premises. Whether you need FTTC, FTTP, or EFM, we handle the survey, procurement, installation, and ongoing management.
SD-WAN & Network Optimisation
Centralise and simplify the management of distributed network connections with SD-WAN. We design intelligent WAN architectures that prioritise critical traffic, improve resilience with failover, and reduce operational costs across multiple office locations.
SIP Trunking & ISDN Migration
With ISDN switch-off approaching, we help businesses migrate seamlessly to SIP trunking. Our engineers manage the full transition — number porting, PBX configuration, and quality testing — with zero disruption to your day-to-day operations.
Unified Communications
Bring voice, video, messaging, and collaboration into a single platform. We integrate unified communications solutions — including Microsoft Teams Direct Routing and cloud PBX — that connect your workforce wherever they are working.
Why Constructive IT for Telephony & Connectivity?
We are carrier-agnostic and vendor-independent, which means we always recommend the solution that is genuinely right for you — not the one that earns the highest margin. Our project managers liaise directly with carriers and technology vendors on your behalf, removing the frustration of dealing with multiple providers.
With experience spanning office relocations, new builds, and multi-site estates, our engineers understand how telephony and connectivity fit into the wider IT picture — ensuring every circuit, handset, and call flow integrates seamlessly with your network infrastructure.
