The basics

What is Mitel Microsoft Teams integration?

It connects your Mitel phone system to Microsoft Teams so people can handle their Mitel calls without leaving Teams. TeamMate does this with PBX Connector: each Teams user registers to their own Mitel SIP extension, and TeamMate automates the Direct Routing link and supplies the session border controllers. It works with Mitel MiVoice and MX-ONE. Your Mitel stays the phone system. Teams becomes the place people use it.

In Teams

What your Mitel users get in Teams.

Mitel calls on the Teams dial pad

Teams Calls becomes a softphone on your Mitel system, using the user's Mitel DID or extension, on desktop, browser and mobile.

Mitel features kept

Hold, transfer, hunt groups and voicemail still run on Mitel. Custom soft keys put the Mitel functions you choose one tap away.

Presence in sync

On a Mitel call, Teams shows On a Call automatically. Presence Pause stops calls ringing through to Teams during meetings.

Voicemail alerts

New Mitel voicemail notifications arrive in Teams, so messages are not missed when people work away from their desk phone.

Screen pops in Teams

Show caller details from your CRM or other systems as a card in Teams before the call is answered. A large financial institution uses this to give agents context on every inbound call.

Pro Transfer

Transfer a Mitel call to any Teams user, with real status updates sent back to Mitel. How Pro Transfer works.

Options

Three ways to connect Mitel to Teams.

Most Mitel and Teams integrations use one of three approaches. They differ in where the call is answered and how many Mitel features come along.

Cross launch

A Teams app opens a separate Mitel softphone. Calls move out of Teams, and you support a second client on every desktop.

Twinning

Mitel also rings a separate Teams number. Calls are answered in Teams, but Mitel features like park, hunt groups and the voicemail indicator are lost, and each user needs an extra number or trunk.

Registration (TeamMate)

Each Teams user registers to their own Mitel extension. Calls are answered in Teams with Mitel features kept, no extra number per user, and the same provisioning you already use for Mitel softphones.

Simultaneous ring

Ring Teams and the Mitel desk phone together.

On MiVoice Business, add each user's Teams extension to a Mitel Multi-Device User Group (MDUG) with their desk phone. A call to the user's number then rings Teams and the desk phone at the same time, and they answer on whichever is closer. See Mitel's documentation on Multi-Device User Groups.

One number, every device

An MDUG groups up to eight of a user's phones under one directory number, so the desk phone, Teams and other devices all ring when that number is called.

Fewer Mitel licenses

Only the prime phone, usually the desk phone, needs a full MiVoice Business IP User License. The group uses a Multi-Device User license instead of a license per device.

One call at a time

When the user is on a call on any device, Mitel treats the others as busy, so a second call follows the user's busy handling instead of ringing Teams.

Value

Keep Mitel. Work in Teams.

Mitel in Teams in three steps.

Set up your portal

FAQ

Mitel and Teams questions.

Does Microsoft Teams integrate with Mitel?

Yes. TeamMate PBX Connector registers each Teams user to their own SIP extension on your Mitel system, so Mitel calls ring on the Teams dial pad on desktop, browser and mobile, with Mitel features like hold, transfer, hunt groups and voicemail.

Do we have to change our Mitel system, numbers or carrier?

No. Your Mitel system, phone numbers, call routing and carriers stay as they are. Teams becomes another endpoint for the same Mitel users, much like a desk phone or a Mitel softphone.

Which Mitel systems does it work with?

TeamMate works with Mitel MiVoice and MX-ONE. It connects over SIP, the same way a SIP softphone does, so each Teams user registers to their own MiVoice or MX-ONE extension. Mitel is among the 80+ PBX types and variants TeamMate has tested. Running another Mitel system? Tell us which one and we will confirm before you start.

Can Teams ring at the same time as a Mitel desk phone?

Yes. On MiVoice Business Release 6.0 or later, add the user's Teams extension to a Multi-Device User Group (MDUG) with their desk phone. Calls to the user's number ring both, and only the desk phone needs a full IP User License. MDUGs are a MiVoice Business feature and are not available on MX-ONE.

Do users need a Microsoft Teams Phone license?

With PBX Connector, yes, as with any Direct Routing setup. If you would rather not buy Teams Phone licenses, the ACS Call App add-on lets users make and take Mitel calls in Teams without them.

Do we need a session border controller (SBC)?

An SBC is needed for any SIP connection to Microsoft Teams, and it is included. TeamMate runs SBCs in 9 Microsoft Azure regions, so there is nothing to install on site.

Does Teams presence stay in sync with Mitel?

Yes. When a user is on a Mitel call, their Teams status changes to On a Call automatically. Presence Pause stops calls ringing through to Teams during meetings or focus time.

Can Mitel dealers sell it under their own brand?

Yes. Dealers and service providers get a white-label portal and a Teams app with their own name and logo, and can provision customers in the portal or through a REST API.

How is it priced, and can we try it?

It is priced per user, per month. Service providers and Mitel dealers can start with a free 30-day proof of concept on their own Mitel system.
