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](#option-1-use-the-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](#option-2-show-your-own-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](https://kb.voipcloud.online/pbx/different/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](https://kb.voipcloud.online/pbx/receive-calls/internal-number/) to the conference, so Teams users can dial it.
3. Connect an [Inbound number](https://kb.voipcloud.online/pbx/receive-calls/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](https://kb.voipcloud.online/teams-and-sip/microsoft-teams/connect-teams-users-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](https://kb.voipcloud.online/pbx/receive-calls/inbound-number/) with the number you want to advertise.
3. Add a [Call diversion](https://kb.voipcloud.online/pbx/accept-make-divert/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.
