This feature requires Lync Plan 3 and Exchange Plan 2.
|
If your version of Office 365 includes Lync-to-phone (Lync Plan 3), you can set up an account with a Lync-to-phone service provider so users can make calls to, or receive calls from, any phone number.
You can also set up Lync-to-phone voice mail by enabling users for Exchange Online Unified Messaging (Exchange Plan 2).
