Age UK's Call in Time service aims to combat loneliness among older people by connecting them with volunteers over phone calls. The charity initially struggled with a manual call system that couldn't scale, but partnered with Reason Digital and Twilio to build a new software-powered solution. This platform automates the vetting process for volunteers, enables faster onboarding, and scales call volume on demand through a serverless architecture. With this revamped service, Age UK plans to reach 10,000 calls per week, making it easier for older people to join and connect with others, often leading to genuine friendships.
