Skype for Business Online Audio Conferencing – Dial out behavior change

06/12/2018 No Comments

Microsoft is making some changes to Skype for Business Online Audio Conferencing Dial Out. To best meet our customer’s business needs, Microsoft is adjusting when attendees can add other participants to a Skype for Business meeting via dial out.

How does this affect us?

Till now, meeting guests are able to add Audio Conferencing attendees at any time.

Going forward, the meeting service will require at least one authenticated user from the organizer’s company to be present in the meeting to allow adding another participant via dial-out. Company attendees can be authenticated through the Skype for Business Client.

This new behavior in meeting dial outs will be rolled out in the next coming days.

What do we need to do to prepare for this change?

You don’t need to do anything, but may consider updating your user training, and notifying your helpdesk.
