There isn't a resource that contains a listing of all of the dial-in numbers for Audio Conferencing. If you are looking to see if there are dial-in phone numbers available in your area or country/region, go to Skype for Business admin center > Voice > Phone Numbers, click Add, and then click New Service Numbers. Use the lists for Country/Region, State/Region, and City to filter your search. Also, if you are looking for toll-free service numbers, select Toll-Free from the State/Region list.
If there is only one phone number available in your organization, it will be used as the default number for all of your users. When multiple phone numbers are available, you can select the default phone number for each user. This default number will be included in Skype for Business meeting invitations.
You can see Set the phone numbers included on invites to change the dial-in phone number for a single user.
Domestic dial-in numbers are dedicated to your organization and are the only ones that can be set as a default phone number. However, international dial-in numbers may be shared across multiple organizations.
We are frequently updating how you can manage features found in Skype for Business Online, so the steps here might be a little different.
