Backed by Barton Telecom’s expert UK-based engineer support, Horizon provides the ultimate future-proof migration path to protect your business communications before the January 2027 PSTN and ISDN line switch-off.

Horizon Handsets & Application Suite
We supply, pre-configure and support the full range of physical endpoints and digital applications optimised directly for the Horizon platform.
– Premium Desk Phones: Full system integration with the Yealink T4 and T5 series (including the T46U and the adjustable-screen T54W). These business-grade units feature Optima HD voice technology, built-in Bluetooth and programmable busy lamp fields (BLF) so receptionists can view staff availability instantly.
– Executive Cordless Units: The Yealink W73P DECT hardware system is built for active environments like warehouses, workshops and automotive showrooms. The handset provides a massive 35-hour talk time and 400-hour standby time, letting staff move up to 50 metres away from the base unit inside the building.
– Horizon Softphone Client: A dedicated communication application deployed as a native desktop programme for Windows and macOS or as a mobile app for iOS and Android. This allows remote staff to make, receive and transfer calls using their primary business landline number from any location with an internet connection.
– Microsoft Teams Integration: Horizon links into Microsoft Teams using direct routing protocols. This native integration gives your staff the operational flexibility of the Teams interface combined with the financial benefit of Gamma’s highly cost-effective outbound call bundles.

- Reliability: Built on Gamma’s own robust IP network with 99.9% availability.
The Infrastructure Behind Horizon VoIP
Horizon runs on Gamma’s own purpose-built UK IP network. Because Gamma controls the entire routing path rather than renting space from another provider, voice traffic gets automatic priority over standard web data. This keeps call quality crystal clear and stops issues like clipping or dropped audio.
– Direct SIP Routing: The system uses Session Initiation Protocol (SIP) to connect your physical desk phones and apps straight to the cloud core without lag.
– Automatic Fraud Protection: Built-in network monitoring tracks call volumes in real time, automatically trapping and blocking sudden traffic spikes or unauthorised international dialling before it hits your bill.
– The Horizon Web Portal: A central dashboard that lets your administrators update hunt groups, swap call routing paths and change music-on-hold instantly. You can manage everything internally without waiting for an engineer call-out.
Frequently Asked Questions
Gamma Horizon is a hosted business telephone service that operates entirely in the cloud. It provides businesses with a complete phone system featuring advanced call routing, mobile twinning and desktop integration without the need for expensive on-premises hardware.
Yes. Barton Telecom manages the entire number porting process behind the scenes. We migrate your existing geographic and non-geographic numbers over to the Gamma network with zero downtime, keeping your business continuity fully uninterrupted before the January 2027 PSTN switch-off.
Through the Horizon Integrator desktop client, the system natively links with over 200 popular business applications. This permits instant click-to-dial functionality and automatic customer record screen-popping for platforms including Salesforce, HubSpot, Zoho, Bullhorn and Microsoft Dynamics.
If your organisation relies heavily on Microsoft 365, Horizon can connect directly into your Teams tenant via direct routing. This maps Gamma’s resilient network and cost-effective outbound call bundles directly into the standard Teams interface, allowing staff to use Teams as their direct Horizon phone endpoint.
Unlike online-only providers, Barton Telecom provides fully managed deployment. Our engineers handle the complete system configuration, custom call flow setups and hardware provisioning. On the day of installation, we deliver comprehensive, practical training sessions for your administrative team and general staff, followed by ongoing UK-based telephone support.
