In Teams, there are two options to enable users to make, receive, and transfer calls to and from landlines and mobile phones on the public switched telephone network (PSTN):
- With Phone System with Calling Plans Microsoft provides the phone number to your users and all PSTN services
- With Direct Connect you can connect your existing PSTN connectivity via an SBC (Session Boarder Controller) to Microsoft Teams.
Calling features in Teams
Calling in Teams supports basic Phone System features, such as call answering and initiating (by name and number) with integrated dial pad, call holding and retrieving, call forwarding and simultaneous ringing, call history, voicemail, and emergency calling.
Calling in Teams is powered by Phone System (formerly known as Cloud PBX), the same service in Office 365 that enables PSTN calling capabilities in Skype for Business Online.
Setup takes minutes, not days, with a dedicated onboarding specialist to ensure installation goes smoothly and preconfigured phones that quickly connect to your existing internet service. Onsite staff, remote workers, and IT will all have access to the same digital tools they need to use and manage business communications through one platform — anytime, anywhere, on any device.
The RingCentral mobile app turns your employees’ desk phones, laptops, tablets, and smartphones into fully functioning mobile offices. It gives them 24/7 access to the company phone system and all its communications and collaboration tools so they can work from anywhere they have internet access.
