Gamma
A Tier 1 UK network operator with its own telecoms infrastructure. Gamma's Horizon platform delivers enterprise-grade hosted telephony trusted by over 100,000 UK businesses.
About Gamma
Gamma is one of the UK's leading business communications providers and a Tier 1 network operator — meaning they own and operate their own telecoms network rather than reselling capacity from another provider. This gives Gamma direct control over call quality, resilience, and pricing.
Their flagship product, Horizon, is a fully hosted cloud PBX that has become one of the most widely deployed business phone systems in the UK. Unity Comms is an accredited Gamma partner, meaning we can deliver, configure, and support Gamma solutions with full technical expertise.
Why Gamma?

Future-Proof
Gamma is at the forefront of the ISDN switch off migration, with VoIP and SIP solutions ready to replace legacy infrastructure before the 2027 deadline.
