When you enable Microsoft’s Voice Licensing, your O365 Team environment can function as a telephone solution for small and medium organizations with up to 300 users. Microsoft continues to improve Team’s voice capabilities. Almost every time you visit the Teams site, you will notice that something has been added or moved to make it easier to use. Most enterprises should be able to migrate to Microsoft Team Phone System voice with little to no loss of functionality from their present system at this stage. For complex call centre solutions and other add-ons, there are numerous third-party possibilities.

Teams Voice Necessitates Three Major Components:

● Teams’ fundamental phone features are provided via the Microsoft Team Phone System. (For example, transfer, hold, park, voicemail, and so on.) The E5 and A5 O365 and M365 licenses include this.

● Domestic or International Calling Plan: This gives you a direct phone number (DID) and minutes to make outbound calls.

● When you send out a Teams meeting invitation, this gives you the dial-in number. The E5 and A5 O365 and M365 licenses include this.

● Microsoft offers the Domestic Calling Plan license for an extra charge if you hold an E5 or A5 license.

● If you have an E3 or A3 or lower license, or one of the M365 Business licenses, you can utilize “Business Voice” to add all three components for up to 300 users.

● If you have more than 300 people, you can use “Teams Calling Essentials” and the Audio Conferencing add-on to supplement 1 and 2.

● Commercial pricing is usually more cost-effective, and non-profit and educational groups may qualify for reductions.

Microsoft Team Phone System will combine the Business Voice and Calling Essentials bundles into one dubbed Teams Phone With Calling Plan after the first of the year. This will set you back and exclude audio conferencing. It appears that audio conferencing will be included in more M365 base licenses.

● Larger businesses that wish to keep per-user expenses low and can manage an on-premise Session Border Controller. SIP trunks can still use direct routing.

● Session Border Controllers interface with Teams Direct Routing. It can also be hosted by third-party SIP providers.
