consistent numbering, emergency calling and compliance recording. Route real- time traffic through SD-WAN or SASE to the nearest media node, with failover that does not drop calls. These are the basics that underpin every successful deployment. They set the stage for the next layer of change, where AI-driven features are starting to reshape how collaboration and contact centres behave and what the network must carry. AI and traffic load AI collaboration benefits are already becoming mainstream. Features already in use include live captions and translation, acoustic echo control, meeting and call summaries, quality diagnostics that spot a bad local network, agent assist that surfaces the right policy while the customer is speaking. These functions clearly improve outcomes for users and customers, but they also change the traffic profile. Some processing can happen on the device, some relies on media nodes close to the user, and some runs best in cloud regions. The result is
more paths to manage, and more demand for stable, low-latency connectivity to keep experiences consistent.
What is changing in the UK? Investment continues across the
ecosystem. Carriers are extending fibre into more locations, lifting backbone capacity and improving diverse routing. Vendors are placing more media nodes closer to users, which helps a great deal. Government programmes for hard- to-reach areas are making progress, although it takes time. Colt is expanding its European fibre footprint, deepening interconnects to major collaboration and CCaaS platforms, and operating SIP trunks and SBCs as managed services with defined media quality targets. Upgrades on international routes, including trials of very high-capacity services, show how far performance can scale. The goal is not just more speed but consistent quality for voice and video, with routing that avoids unnecessary detours and resilience that maintains service during faults.
