Hosted Telephony

The future of connectivity

The combination of improvements in connectivity, the flexibility of SIP trunks and the ongoing demise of ISDN, along with BT announcing a target end date of 2025, make Hosted Telephony the logical choice when you’re looking to replace your existing system.

With communication embedded as a fundamental element of the ICT environment, experts at TSG boast an in-depth understanding of all the components required to deliver a successful hosted solution including WAN, voice and data connectivity requirements.

osted Telephony

In simple terms, hosted telephony is a telephone system that resides in the cloud rather than your office, removing the need for a PBX, with calls made and received over a broadband connection.

Head office and branch office locations connect to the Gamma Horizon cloud platform via an assured connection service (shown in green on the diagram above). This guarantees the call quality and performance.

Roaming users connect using softphone clients over whatever bandwidth they have available at their location (shown in yellow on the diagram).

The calls are managed and controlled centrally by the Gamma Horizon Hosted Telephony platform and inbound and outbound calls are passed to the normal voice (PSTN) network (shown in grey on the diagram) for all communication outside the organisation.
