Whether you are multinational looking for global voice solutions that bring multiple services together on a single network (landline and data), or an indigenous firm with multisite requirements, BT Ireland will help you stay competitive in an increasingly connected world. As voice becomes another application in a growing armoury of communications tools, we will secure its place at the heart of your organisation – it’s still the preferred channel for many businesses and their customers – while integrating it with new services as they evolve.

We help harness the full power of Internet Protocol for Voice over IP and IP telephony, enabling your employees to take calls anywhere using any device – laptop, tablet, fixed or mobile phone. We will take you on a journey that starts with the convergence of voice and data, providing a stepping-stone to Unified Communications and new collaboration tools.

Everyone is starting from a different place, which is why BT builds bridges between old and new systems, migrating you from traditional telephony and older network technologies to the new, at your pace in parts of the business that you choose. We also give you the option of running old and new systems in tandem, bringing them together over time when it makes sense financially and strategically.
