Why COLT unified communications?

We understand your needs

From the very beginning, we’re in it together. We’ll work tirelessly with you to discover how you can make the most of your infrastructure right now and how you can prepare for new technology in the future.

This level of service doesn’t stop at installation. Our managed services are backed up with stringent SLAs. We ensure a consistent service with a single point of contact. And we offer total support on the ground from expert local staff. We even have a Frost & Sullivan 2007 Award for Best Customer Service to prove it.

We go further

COLT operates and manages network infrastructure spanning most of Europe. We reach 13 countries, 34 cities and over 14,000 buildings. Plus we have high-quality links with the rest of the world.

Our superior metropolitan coverage also means we can offer a faster service, with better coverage, across the majority of European metro areas.

We also have a large and diverse portfolio of products which means, over time, you can start to implement more and more feature rich and value add applications.

Simply, we have the knowledge, experience and capability to make unified communications work for your business.
