• The number of user (subscriber) numbers obtainable from Microsoft equals the total number of Domestic and/or International Calling Plan licences multiplied by 1.1 plus 10 extra numbers, pay-as-you-go licences allow only 1 number each, and these limits exclude numbers that are ported or porting to Microsoft. in context
• New numbers are acquired through the Teams admin center Add phone numbers wizard under Voice > Phone numbers > Add > From Operator, and the Voice option only appears once at least one Enterprise E5 or E3 licence, one Phone System add-on licence, or one Audio Conferencing add-on licence is owned. in context
• At least one Microsoft Calling Plan license must be assigned in the tenant before phone numbers can be acquired from Microsoft. in context
• Toll and toll-free service number quotas are tiered by the tenant's total Teams Phone and Audio Conferencing licenses, from 5 numbers for 1-25 licenses to 1,500 numbers for 50,000 or more (for example 51 licenses yields 20). in context
• A tenant can acquire user (subscriber) numbers equal to its Domestic plus International Calling Plan licenses times 1.1 plus 10, plus one number per Pay-As-You-Go license; ported numbers do not count against this limit. in context
• The Calling Plans limits on how many phone numbers a tenant can acquire do not count numbers that are ported or being ported to Microsoft. in context
• Microsoft Teams Calling Plans require pay-as-you-go billing (Communications Credits) to reserve and use toll-free phone numbers. in context
• Microsoft grants toll-free service numbers in tiers by the count of Teams Phone and/or Audio Conferencing licenses, for example 5 numbers for 1-25 licenses, 20 for 50-99 and 125 for 1,000-1,249; ported numbers do not count against the limit. in context
• In the Teams admin center, toll-free numbers from Microsoft are ordered with a service usage type (Dedicated conference bridge (Toll Free), Call Queue (Toll/Toll Free) or Auto Attendant (Toll/Toll Free)) rather than as user (subscriber) numbers. in context
