PHONE SYSTEMS
Microsoft Teams Calling for Australian Businesses
Make and receive business calls from Teams. We connect Microsoft Teams to the phone network with Direct Routing, so your team can use one app for chat, meetings and calls.
Teams as your business phone
Teams Phone turns Microsoft Teams into a full business phone system. In Australia, Teams connects to the public phone network through a carrier using Operator Connect or Direct Routing.
We provide Teams Direct Routing as part of tsit.cloud, so you can keep your numbers and choose how staff use it: Teams only, or Teams alongside desk phones.
Telstra Calling for Office 365 is being withdrawn on 30 November 2026. If you use it, we can move your numbers and calling without rebuilding your Teams setup.
