Making calls with Teams: What is important before the changeover.

Phone numbers, licenses and call processes: How to prepare for the change in your business telephony.

Collaboration in a digital workplace

Anyone who already uses Teams for meetings often also wants to make business calls there. The interface is familiar. To ensure a smooth transition, some basics still need to be clarified.

Take up today’s ways of talking

Write down what happens when someone calls your main number. Does a device or an entire team ring? Is there an announcement? Who takes over during lunch breaks or during holidays? These everyday details determine whether the new telephony works well.

Also consider devices that are easily forgotten: for example, door intercoms or other systems with a telephone connection. You may need a separate solution.

Consider technology and contracts together

peoplefone offers multiple connection paths for Microsoft Teams, including Direct Routing and Operator Connect. These differ in setup and operating model. Which variant is suitable must be checked together with the required licenses and the existing contracts.

Create a complete list of phone numbers and check responsibilities, notice periods and the planned porting date. A premature termination can make the transition unnecessarily difficult.

Test with a small group

Before changing the entire company, it is worth having a pilot with people from different roles. Test incoming and outgoing calls, transfers and substitutions. Let those involved try out the intended headsets or phones in an actual work environment.

  • Is the main number working as intended?
  • Are calls distributed correctly in case of substitution?
  • Is the behavior outside opening hours clear?
  • Does the team know how to relay conversations?

Also discuss the exceptional case

Accessibility should not only become an issue when there is an internet outage. Discuss which alternative routes are needed and what options the chosen solution offers. Record who can make changes in the event of a disruption.

Plan the transition from the perspective of a calling customer. The new technology should mean one thing above all to him: he can continue to reach the right person.
