Case Study: TalkTalk Business achieves scalable, high‑availability Microsoft Lync deployments with KEMP Technologies LoadMaster

Building a scalable communications platform with Microsoft Lync & Kemp

TalkTalk Business, a fast‑growing UK B2B operator serving more than 180,000 enterprises, needed a scalable, affordable load‑balancing solution to support customers migrating from legacy PBXs to Microsoft Lync. After evaluating several vendors, TalkTalk Business selected KEMP Technologies and its LoadMaster family because it was Lync‑certified, easy to deploy and manage, provided a free evaluation unit, and avoided the upfront purchase commitments required by other suppliers.

KEMP Technologies implemented LoadMasters in TalkTalk Business’s Lync lab and customer environments to distribute traffic, provide high availability, and act as a reverse proxy replacing end‑of‑sale TMG functionality. The result was predictable, reliable uptime (Rodgerson notes it “works 100% of the time”), faster deployments with KEMP’s Lync templates, and a scalable solution for customers typically with more than 150 Lync seats. KEMP LoadMasters are now TalkTalk Business’s exclusive load‑balancing partner, with units priced around £8k–£10k and broadly certified for Microsoft Lync and Exchange.
