BT One Voice

A single service that cuts costs dramatically by consolidating voice and data onto one network

What is BT One Voice?

Voice becomes another application on the network, leveraging Internet Protocol for Voice over IP, and IP telephony that allows users to take calls anywhere using one number on any device – laptop, tablet, fixed or mobile phone. Run across your own VPN (Virtual Private Network), BT guarantees a robust and consistent service tailored to specific business needs, domestic and international.

Why now?

To stay competitive in an increasingly connected world, organisations need cost-effective telephony that offers more features and functionality. BT One Voice also opens the door to the convergence of voice and data, providing a stepping-stone to Unified Communication and Collaboration (UC&C) services that encompass new collaboration tools.

How do you start?

BT will build a bridge between old and new systems, taking you from traditional telephony and older network technologies to IP at your pace in parts of the business that you choose. You can run old and new sytems in tandem and converge them over time.

The benefits of BT One Voice

Fast return

Moving to IP delivers a fast return on investment as costs tumble, particularly on overseas and mobile calls that you can keep on your VPN.

Simplicity

Make “adds, moves, and changes” quickly and easily without incurring any extra costs and let BT manage multiple sites as an all-in-one service.

Integration

One size doesn’t fit all in networks and telephony, which is why BT will integrate whatever you have with what the business needs.

Future-proof

A first step in convergence, the adoption of IP networks is necessary for any organisation that wants to explore Unified Communications and Collaboration.
