No need to assign individual addresses for your remote workers.  Assign addresses based on their closest office location.

To assign a number to a user or resource account, ensure that the user / account has the appropriate voice licence. 

Also check that they do not have a calling plan license.

Ensure that your user is licensed for the country you want to assign the number from.  E.g. they need to have a UK license when you want to assign a UK number eg +44.

For now, this is only available on Skype for Business.

Users that need Operator Connect Conferencing numbers to join the meetings that they organise need to have an Audio Conferencing Standard subscription license or an Operator Connect Conferencing license assigned to them.

Once we complete your order, we'll upload numbers to your tenant. You can view the numbers in the Teams admin center by going to Voice > Phone numbers.

Assign numbers to your Audio Conferencing bridge. You can assign numbers to your Audio Conferencing bridge from the Teams admin centre under Meetings > Conference Bridges > Add.

You can apply Audio Conferencing Routing policies at the user level, meaning we route only the outbound calls from Teams meetings organized by users with the associated policy. You can also apply these policies at the global level, meaning we route outbound calls from Teams meetings organised by all users in your organisation.
