Microsoft Teams Calling

Make and receive real phone calls to landlines and mobiles directly inside Microsoft Teams, using your business number.

If your team already lives in Microsoft Teams for chat and meetings, Teams Calling (Direct Routing) connects it to the regular phone network as well – so staff can call any landline or mobile number, and receive inbound calls, straight from the Teams app they already have open, using your existing business number.

This suits businesses that want to consolidate onto one app rather than running Teams for internal communication and a separate phone system for external calls.

Setup runs through Direct Routing, which connects your existing Microsoft 365 Teams tenant to the regular phone network via VOIP24. We handle the technical configuration on our end; on yours, it mostly comes down to confirming your Teams licensing already includes calling, which we check before anything is set up.

Staff keep using the Teams app they already have open for chat and meetings, with calling added as another tab rather than a separate application. Desk phones aren’t excluded – someone who wants a physical handset for calls while a colleague prefers to answer from Teams on their laptop can both work from the same business number.

A professional services firm that already runs entirely on Microsoft 365 is a typical fit: staff are already in Teams all day for meetings, so adding real phone calling there removes the need for a second phone system and a second app just for taking calls.

Key features

  • Call any landline or mobile from within Microsoft Teams

Frequently asked questions

Do we need a specific Microsoft 365 plan for this?

Teams Calling via Direct Routing needs a Microsoft 365 plan that includes Teams with calling capability. We check what your current licensing already supports before any setup begins, so there are no surprise plan upgrades needed partway through the process.

Can we keep our desk phones as well as Teams?

Yes - desk phones and Teams calling can run side by side under the same business number. Someone who prefers a physical handset and a colleague who answers entirely from their laptop in Teams can both work from the one phone system without conflict.

Does every staff member need Teams calling enabled?

No - it can be enabled only for the staff who actually need outbound/inbound phone calling through Teams, while others keep using Teams for chat and meetings only, or use a desk phone instead, without extra licensing for people who don't need it.
