How is the Microsoft Phone System different from other PBX?

Microsoft Phone System is a cloud-native service. It costs a fraction of the investment required to install and maintain the infrastructure on an on-premises exchange. Moreover, users can access it from any device of their choice as long as it is connected to the internet. It has a 99.9% guaranteed up-time that is difficult to achieve with on-premises PBX systems.

Is Microsoft Phone System a replacement for Microsoft Teams and Skype for Business?

No, Microsoft Phone System is not a replacement for either of the applications. It enhances their capabilities by allowing users to perform tasks like placing, receiving, transferring, muting and unmuting calls on phones from a unified UI within Microsoft Teams or Skype for Business to deliver an integrated experience.

How does the Microsoft Phone System connect calls outside an organization?

Microsoft Phone System is a cloud PBX that replicates the functioning of regular private on-premises exchanges. It links with a PSTN to connect calls. This can be done either through direct routing involving a third-party carrier or by using one of the Calling Plans offered by Microsoft.

What is needed for using the Microsoft Phone System?

Businesses must use either Skype for Business or Microsoft Teams as their communication and collaboration platform. While businesses with Office 365 Enterprise E5 get Microsoft Phone System by default, it is compatible with other versions like Enterprise E3 and E5 as an add-on plan for $8.00/user/month on an annual commitment. Organizations must use a phone system with VoIP capability and need to choose between the Calling Plan, Direct Routing, or their combination for inbound and outbound calls.
