If you have PSTN enabled for Skype for Business does it also work for MS teams?

If you have PSTN or Microsoft Skype for conferencing enabled for Skype for Business does it also work for MS teams? The problem is I do have PSTN feature for SFB and when I create SFB meeting Outlook I do see dial-in number included in meeings, however, when I create meeting using MS teams Outlook add-in dial-in number is not included?

I did some search online and wonder if my organization needs to separately enable PSTN for MS teams.

https://docs.microsoft.com/en-us/microsoftteams/configuring-teams-calling-quickstartguide

None of my co-workers who have SFB PSTN enabled see dial-in number included in meetings created via MS teams Outlook plugin? Any insight on this will help.

Conferencing enabled for SFB won't work for MS Teams.
You have to get it subscribed separately for MS Teams, then only dial-in numbers will appear when you create teams meeting.

Thanks for reply. Can you please direct me to any Microsoft page which clearly states that. Just to make it more official coming from Microsoft so I can share with others.

How do conferencing bridges work?
When you are setting up Audio Conferencing for Skype for Business or Microsoft Teams, you will get an audio conferencing bridge. A conferencing bridge can contain one or more phone numbers. The phone number you set will be included on the meeting invites for Skype for Business and Microsoft Teams apps.

Still little confused as what Microsoft link above states is different than what you stated?

Hi newhdanalyst,

If you want to realize this, it needs to configure direct routing.

Microsoft Phone System Direct Routing lets you connect a supported, customer-provided Session Border Controller (SBC) to Microsoft Phone System. With this capability, for example, you can configure on-premises Public Switched Telephone Network (PSTN) connectivity with Microsoft Teams client.

For more details about direct routing, you could read the following two articles:
