Rudy Evens, CEO, Tectum Group

Tectum Group


  • Tectum Group faced challenges in expanding its legacy communications solution to onboard new sites and companies, which was a significant issue given the group’s fast pace of growth through acquisitions.

  • A new solution offering greater flexibility and simplicity was urgently needed to facilitate efficient communications across all Tectum Group sites.

Products & Solutions


  • The Cloud-based solution enables speedy onboarding of new company sites within a matter of weeks.
  • Management is simplified, with one trained Tectum Group technician able to manage everything centrally.
  • Transparent software upgrades keep the solution up-to-date, enabling the timely deployment of new features.


  • OTEC supports Tectum Group’s growth strategy by facilitating efficient communications across sites and ensuring new acquisitions are connected to the rest of the group as quickly as possible.
  • The monthly use-based pricing offers complete cost transparency.

User Experience:

  • Migrating the legacy Alcatel-Lucent OmniPCX® Enterprise solution to the cloud means users have retained the same interface they are used to. Most do not even realize the solution has become cloud-based.
  • Employees across the group can reach one another efficiently thanks to the easy-to-use extension directory. 
  • The ability to create groups with OTEC supports better communications and teamwork.
  • The solution delivers a standardized user experience across all sites.
