Achieving digital transformation without interrupting collaboration

How Sipcom helped a 500+ employee U.S. company reduce costs, save time, and improve efficiency by completing their unified communications upgrade.


An established U.S. based IT training company is embarking on a transformative journey to upgrade its communication infrastructure by migrating a portion of its users from its legacy PBX platform to Microsoft Teams.

This strategic move is driven by the company’s desire to embrace modern communication technologies, enhance collaboration, and deliver a seamless experience to both its employees and clients. To ensure a smooth transition, the company aims to run both the legacy PBX and Microsoft Teams simultaneously during the migration process and after as a subset of users will still be using the legacy platform. As the company only has a small IT department, they also require ongoing Teams Tenant Support once the migration is complete for continuous operational excellence.
