Calling for Microsoft Teams is next upgrade resized

'Calling for Microsoft Teams' is the next upgrade step for business using Teams

13 Oct 2021

For value and functionality, available through one interface, Microsoft Teams is head and shoulders above other UCaaS solutions, but it does lack one key element - built-in telephony at its core.

When 'Calling' is added, Teams transforms from an excellent internal communication tool, to a highly capable business phone system.

Telephony is essential for true Unified Comms

Wait, I can hear you saying, I can make phone calls on Teams. Yes you can, but only in a very limited way.

Out-of-the box, Teams supports the ability for users to make voice over IP (VoIP) calls from Teams client to Teams client. 

It does not allow calls outside of the Teams environment.

If you want your users to be able to call regular phones you will need to upgrade your Microsoft licensing.

Microsoft offers Phone System - formerly known as Cloud PBX - as its Teams telephony bolt-on.

Phone System offers fairly basic features, such as call answering and initiating (by name and number) with integrated dial pad, call holding and retrieving, call forwarding and simultaneous ringing, call history, voicemail, and emergency calling.

However, while it does offer this basic functionality, it doesn’t provide the enterprise-quality voice capabilities that most enterprises require. 


What are my Teams Calling options?

By adding cloud telephony to Teams, you can provide consistent user experience for external and internal communications.

That means external phone calls can be made from the same Teams interface used for chat, internal meetings, file-sharing and other cloud services, offering greater convenience and improved productivity for employees.

To plug the telephony gap in Microsoft Teams, there are not too many options to choose from.

In Australia, two of the key vendors are Access4 and Telstra.

Both vendors have built their cloud telephony for Teams product on the Cisco BroadWorks platform.


Access4 for Teams Calling

Access4 Calling for Microsoft Teams is more than just direct routing. It is a full cloud telephony solution designed to integrate seamlessly with Teams and with the ability to tailor features to specific business roles.

Collaborative roles utilise video telephony and basic call features, while call-intensive roles such as customer support and sales might choose access to advanced telephony features and call queues synced across their preferred devices.

Access4 is an Australian vendor, founded in 2016, specifically to develop cloud telephony for UCaaS environments. The Access4 solution is centred on the Broadworks™ platform, and leverages an in-house developed OSS/BSS platform called SASBOSS™ to provide visibility, management and reporting.
