On-Phone, is an easy to deploy, advanced hosted telephony solution that scales from 1 to 100,000's of users.

Based on the world leading PortaSwitch platform from PortaOne (which has over 20 million current connections) On-Phone delivers a highly resilient, full-feature VoIP telephony solution for any size business

Introducing On-Phone

The constraints, cost and management of  traditional on premise phone system, comprising a PBX and physical hardware, no longer meets the demands for a modern business.
Upgrading these systems involves downtime and significant investment. Fluctuating user numbers and reliance on legacy phone lines is restrictive and inflexible.
We offer the perfect solution, an off-premise, UK hosted, and highly secure system deployed as a Cloud/Hosted service. It is designed to make the deployment and management of a comprehensive, full function phone system as hassle free as possible.
On-Phone is easy to deploy and suitable for businesses of any size. The On-Phone system is located in ISO27001 tier 1 data centres, across 2 locations, accessed via the internet.

Users can access On-Phone from anywhere, on any device, at any time.

Users benefit from familiar telephone features plus new capabilities that significantly improve productivity, teamwork and organisational
flexibility. Businesses gain fully compliant (PCI and MiFID II) call recordings, advanced management and analytics, and with a range of delivery options and service bolt-on's, can fully integrate with other business systems, such as CRM and Skype for Business.
