The client is a Fortune Global 500 company specializing in digital automation and energy management. They combine energy tech, real-time automation, software, and services to provide solutions for homes, buildings, data centers, infrastructure, and various industries.

As a longtime Avaya managed services client, our client was looking to move from Skype for Business to Microsoft Teams for collaboration to achieve a holistic voice and collaboration solution that would be seamless for their employees.

CBTS solution
CBTS voice experts assessed the client’s environment, then developed and implemented a strategic plan to move the company to Microsoft Teams for collaboration, delivering PSTN voice calling to Microsoft Teams via Direct Route.

Company employees can now work from their chosen device at any location, dramatically improving production and collaboration.

Our client, founded in 1883, is the largest grocery retailer in the U.S. with over 3,400 store locations.

The retail grocery client was interested in testing the Microsoft Teams Phone system for a subset of IT department users and getting hands-on experience managing call routing in the Teams phone system.

CBTS solution
CBTS completed a trial agreement that delivered PSTN Voice into the client’s Microsoft Environment via Direct Route. This proof of concept allowed a small subset of users to test the PSTN calling experience in Teams and their IT staff to test their experience managing the call routing in the phone system. Based on the trial’s success, the client elected to move forward with a Microsoft Direct Route solution from CBTS.

Employees can now work from any device anywhere in the world, dramatically improving productivity and collaboration. The client now has a go-to partner to assist with future needs related to the Teams Phone system.
