Voice over Internet Protocol (VoIP) has transformed the way businesses communicate. Unlike traditional phone systems that rely on copper lines, VoIP transmits voice data over the internet. This shift enables more flexibility, scalability, and cost efficiency—essential qualities for businesses in a competitive, digital-first world.
At its core, VoIP converts voice into digital packets, allowing calls to be made from anywhere with an internet connection. For businesses, this means eliminating the need for physical phone lines, reducing maintenance costs, and integrating communications into broader IT systems. VoIP also supports features like voicemail-to-email, call forwarding, video conferencing, and integration with CRM systems—offering greater productivity and professional capability.
Two standout solutions in the VoIP space for businesses in the UK are Gamma Horizon and Gamma PhoneLine+, each designed to meet different organisational needs.
Gamma Horizon: Hosted VoIP for Medium to Large Businesses
Gamma Horizon is a cloud-based VoIP platform tailored for medium to large businesses looking to centralise and streamline their communications infrastructure. It offers a comprehensive hosted PBX system, removing the need for on-site phone servers.

One of Horizon’s key strengths is its scalability.
