Summary

This chapter was all about phone numbers in Microsoft Teams. We began by choosing a PSTN solution for our telephony needs.

Next, we ordered and managed our phone numbers and service numbers. We learned that users need a Calling Plan or Communications Credits licenses assigned and that we can create audio conferencing, auto-attendant, or call queue service numbers.

Then, we configured emergency addresses to associate with our user phone numbers so that when our users call from our environment, that address information can be made available to responders. We also covered emergency calling and call routing policies.

Next, we learned how to manage those user phone numbers and assign/unassign them to users and resource accounts.

In the next chapter, we'll look more closely at managing Phone System in Microsoft Teams and diving into resource accounts more thoroughly.
