How does Phone System work?

Microsoft’s Phone System allows organisations to shift away from on-premises PBX hardware to cloud-based solutions. Businesses using this technology see benefits to employee engagement, productivity and cost. This guide answers the most frequently asked questions, to help you decide if the Phone System is right for your organisation.

What is Phone System?

Microsoft’s Phone System is a cloud-based unified communication platform. It allows users to make phone calls outside their organisation over the PSTN phone network. 

Microsoft Phone System offers a compelling replacement for legacy phone set-ups. It gives you full PBX capabilities, without the complex and costly hardware requirements. Phone System extends the VoIP capabilities of Microsoft Teams – beyond making and receiving calls to a complete business phone system. Delivering the advantages you’d expect from a cloud environment.

Integrating with the Microsoft 365 productivity suite, Phone System also offers feature extensions that integrate with non-Microsoft products.

Another important advantage is the platform’s capability to scale from a single site outfit to a global entity. It easily adapts to your telephony needs as your organisation grows. Whether that growth represents changes in the number of your employees, offices or territories. So, for global organisations, Phone System may prove an especially smart move.

FAQs on using Phone System

How does Phone System work?

Microsoft Phone System enables call control and PBX capabilities in the cloud with Teams and Skype for Business Online. So you can replace your enterprise’s on-premises PBX with a suite of features delivered from Microsoft 365 or Office 365.

Some users may be worried that moving to the Teams Phone System means they have to invest in a shiny new headset to make or receive calls. However, Phone System users can use their mobile devices or a headset with their laptop or PC. Teams and Skype for Business Online compatible IP phone can also be utilised.

Phone System administrators can manage and configure calling options and settings from the same console used for messaging and collaboration.

What size business is best suited to Microsoft Phone System?

From SMEs to corporations, any organisation currently using Teams for collaboration will benefit from adding the Microsoft cloud telephony component. It’s flexible and scalable. Users get a single unified interface for internal and external communication. For IT departments, Teams Calling eliminates complexity and cost from their operations with little incremental cost.

Can Microsoft Phone System replace your existing on-premises PBX hardware?

Yes. A cloud telephony solution like Microsoft Teams Calling gives you full PBX capabilities. Provided you have internet connection, you get all the PBX functionality. But without the drain on staff resource and the maintenance costs associated with legacy hardware.

What do I need to set up Microsoft Phone System?

To use Microsoft Phone System for external calls, you need:

Microsoft Teams + Phone System + PSTN (Calling Plan or Direct Routing from a service provider).

Assigning a Phone System license to a user follows the same steps as assigning a Microsoft 365 or Office 365 license.

Microsoft recommends that organisations looking to migrate to Phone System check the Audio Conferencing and Calling Plans availability for their region.

If Calling Plans are not available for your region, Direct Routing will connect your on-premises telephony infrastructure to Phone System.

PSTN replacement is needed to provide local inbound numbers, number porting and emergency call routing. Organisations will need full PSTN replacement for all employees in all locations. To provide PSTN replacement, an organisation must either partner with a local carrier or be registered as a local carrier themselves. 

PSTN replacement is a complex task for a non-industry enterprise. IT leaders often look to a cloud telephony provider like LoopUp to successfully oversee the regulations for them.

How much is Microsoft Teams Phone System?

This depends on your starting point and the size of your organisation. Microsoft Phone System is either included or available as an add-on with most Microsoft 365 plans.

Added license available:

Microsoft 365 and Office 365 E1 and E3.

Included as part of Microsoft bundle:

Microsoft 365 E5, Office 365 E5, and Microsoft 365 Business Voice licenses.

For organisations already using Teams for collaboration, adding the telephony component makes sense.
