ITP has used Teams as a communication and collaboration app for sometime now. We use it for project planning, file storage and having our weekly team meetings. As our workflow has become more and more centralised around Teams we thought why not take the plunge and use it as our Telephone VOIP app as well.
After some configuration we are now able to make an receive external calls through Teams, while also still using it for internal calls and meetings. This means we have been able to remove our old software and integrate all into one package.
