Gamma Network

The Gamma network is one of the UK’s largest tier 1 providers of voice and data services, switching more than 800 million minutes per month over our soft switch infrastructure. Our Next Generation architecture which interconnects to BT at 650 local exchanges has been specifically designed to:
- Support the end to end automation of customer transactions between our network platforms - Facilitate the rapid development and deployment of new product functionality - Ensure high levels of system availability via multiple layers of technical and geographic resilience. - Interconnect with a range of ISPs and community based networks such as JANET.
We offer a wide range of data products and Horizon can be offered in conjunction with one of our data services. For small site offices, we offer a range of voice focused and guaranteed connections through our IP Assured or Converged Broadband range, whereas for head offices or larger deployments requiring data access, also fully converged Ethernet and Ethernet over the First Mile (EFM) solutions are available.
By using our access solutions, the voice traffic does not leave our network when making or receiving calls, ensuring our focus on quality business IP connections is provided on every call. If an issue does occur, the customer only needs to make one phone call, to our service teams who have sight of the entire call route and are in complete control of resolving the end user’s issue.
