Microsoft Teams Phone refers to the Teams telephone service. It can be used as a VoIP phone system to handle an audio or video phone call whether they’re using a landline, mobile phone, or the Teams app.
What is Microsoft Phone System?
Microsoft Phone System refers to Microsoft’s hosted telephone service that gives you call control and Private Branch Exchange (PBX) capabilities, with options for connecting to a Public Switched Telephone Network (PSTN).
Because Phone System is a part of Teams, you can easily use the service with an IP desk phone. You can also turn any computer, or mobile device into a phone with which to use your Business Voice phone number.
Some organizations need more advanced features that Microsoft Phone System alone cannot offer, such as integrated SMS capability and real-time, single-system analytics. 8x8 can enhance the native Teams Phone functionality, turning it into a powerful, enterprise-level unified communications solution.
With the integration, users can make (and receive calls) internationally directly from the native Teams dialer. 8x8 provides phone numbers in over 120 countries, a direct PSTN replacement in 48, and unlimited calling plans in 47.
Those 8x8 calling plans can also be a more cost-effective telephone solution than using Teams Phone by itself. Although Teams calls are free, expensive add-ons for international calling and SIP trunking can quickly increase overall costs.
What is 365 Business Voice?
Microsoft 365 Business Voice turns Microsoft Teams into a powerful and easy-to-use telephone system. It replaces traditional telephony providers and on-premises PBX systems.
With 365 Business Voice you can host video meetings, set up both toll and toll-free numbers, call menus to help callers get to the right department, and access lots of other useful features and add-ons. 365 Business Voice does all of this by bundling together Microsoft Phone System features into one easy-to-manage service.
In short, Phone System refers to the virtual infrastructure or hosted system, while 365 Business Voice refers to the specific service package that offers Microsoft Phone System and other telephony features.
