Requirements for using the Teams Connector

While the Teams Connector makes linking Microsoft Teams and a SIP trunk a breeze, multiple service providers are involved, each with their own requirements. To help you keep track, here are the prerequisites for using the Teams Connector.

Microsoft Teams licenses

Each Microsoft Teams account that is supposed to be able to make calls via the Teams Connector or the linked SIP trunk requires a corresponding Microsoft license in each case.

This license must include not only Microsoft Teams, but also the "Teams Phone" add-on, which is usually subject to an additional fee.

The most common licenses are:

  • Microsoft 365 Business Basic / Standard / Premium
  • Microsoft 365 E1 / E3 / E5 / F1 / F3
  • Office 365 E1 / E3 / E5 / F3

Microsoft 365 / Office 365 E5 includes the "Teams Phone" add-on.

Special licenses exist for government entities, non-profits, and education. Feel free to contact us for more information on those.

One license for initial setup

During the initial setup, a temporary easybell user is created in Microsoft Office. To accomplish this, the associated Microsoft tenant must contain at least one unassigned license. After installation, the account is automatically deleted and the license can be reassigned.

SIP Trunk of a certified provider

To access the public switched telephone network (PSTN), you need a SIP trunk. We are continuously working to certify additional SIP providers for use with Teams Connector.

Currently, you can use SIP trunks from the following providers:

Alternatively, you can use our generic template to enter your SIP access data. This way, almost all SIP trunks worldwide can be integrated.

No parallel use of similar solutions

The Teams Connector can only be billed properly if no other solutions are used with the Microsoft client that connect external SIP trunks to Microsoft Teams.
