One of the most frequently asked questions here at the CSP Helpdesk revolves around how to add a dial-in number to Skype or Teams meetings. Many users would like to not be required to take the call/meeting at their computer or desk and would rather take the call on the road or somewhere remote.

By following these steps this will allow the host of the meeting to include a dial-in phone number so invitees of the meeting will have the option to either dial in or to take the call from the app.

Ensure your Country or Region is supported for Audio Conferencing on this site.

Each user must meet the prerequisite of having assigned:

    • Microsoft 365 License
    • Microsoft E3 License
    • Microsoft E5 License

For every user that needs a phone number to dial in for their Skype/Teams meeting an Audio-Conferencing Add-On License will need to be procured from customer.cspboss.com.
