Teams audio conferencing

There are two ways to run audio conferences with Microsoft Teams users. Pick the one that suits you:

Option	What you get	Microsoft licence needed
PBX conference room	A conference room in your PBX. Teams users and outside callers dial in to the same call. No Teams meeting link.	None extra.
Your number on Teams meeting invites	Microsoft’s audio conferencing with your own business number as the dial-in, instead of Microsoft’s default number.	Microsoft audio conferencing licence for meeting organisers.

Option 1: use the PBX conference room

The Conference object is a conference room in your PBX. Teams users dial its internal number, and people outside your business call its phone number. Everyone joins the same audio conference.

1. Go to the PBX tab and drag Conference from the Different group onto the canvas. Click the gear icon, enter a Name and, if you want one, a PIN code (optional), and click Save.
2. Connect an Internal number to the conference, so Teams users can dial it.
3. Connect an Inbound number with the phone number outside callers will dial.
4. Click Apply configuration.

Teams users need direct routing set up and their account connected in the PBX to dial the internal number.

Option 2: show your own number on Teams meeting invites

When an organiser with the Microsoft audio conferencing licence creates a Teams meeting, the invite shows Microsoft’s dial-in number for your country. You can advertise your own number instead and divert it to Microsoft’s number.

Divert your number to the Microsoft dial-in number

1. Find the default dial-in number shown on one of your Teams meeting invites.
2. In the PBX tab, add an Inbound number with the number you want to advertise.
3. Add a Call diversion with the Microsoft dial-in number, and connect the Inbound number to it.
4. Click Apply configuration.

Diverted calls to the Microsoft number are charged as outgoing calls on the system-wide default pay-as-you-go call plan. See your service terms for rates.

Change the number on each invite

Note

Menus can change between versions. If a label is different, check the vendor’s own help.

1. In Outlook, click New Teams Meeting.
2. In the invite, right-click Microsoft’s dial-in number and choose Edit Hyperlink.
3. Change the number, and its link, to your advertised number. Then send the invite.

Check it works

• Option 1: call the conference’s phone number from a mobile, and dial its internal number from Teams. You should hear each other.
• Option 2: call your advertised number from a mobile. You should reach Microsoft’s audio conferencing service.
