This is what I found from a website online. It worked well in my environment.
Microsoft having released native Dial-in conferencing into Office 365 to the masses is now taking the world by storm. More and more of my customers are now adopting Skype for Business Online with PSTN Conferencing as their number one choice for Non-Enterprise Voice workloads. When you enable a user for PSTN Conferencing the PSTN number is chosen based on the user’s location. They are also assigned a Conference ID and PIN. This information is emailed to the user by the tenant when they are enabled, like so:
This information is also available in the Skype for Business Online admin console, when you select a user.
However, customers ask if there is a way in which this information can be extracted, so the service desk have a quick reference point of the current configuration settings for users to help service tickets.
There is no way in the tenant to export this information, so I wrote a pretty basic PS script to export the information to CSV.
- You must have the Skype for Business Online PowerShell Module installed on the computer in which you run this script
- You must have access to a tenant Global Administrator account to run the commands
Script logs in to tenant, exports all users PSTN Conferencing Settings to CSV file located in the root of C:\ called O365DialinConf.csv You can change the location if you wish.
There is nothing massively complicated about it, really quite basic, but it helps during service handover.
Finished file (apologies for black out info, customer tenant used)
