How to Leverage Microsoft Teams for External Calling

Person using Microsoft Teams External Calling while working remotely

As Microsoft Teams’ popularity increases, there’s still one feature companies were missing: external calling. Until now.

The increase in remote work is driving people to Microsoft Teams

Between April and October 2020, Microsoft grew from 75 million daily active users to 115 million daily active users.

This 50% increase in users in just a few months means Teams is Microsoft’s fastest-growing business app ever.

“Teams is Microsoft’s fastest-growing business app ever.”

Microsoft, “Microsoft Viva: Empowering every employee for the new digital age”, February 2021.

One factor accelerating this growth is that Microsoft has been steadily improving the user experience and adding features. For example, Microsoft launched Together Mode in 2020, which the NBA used to bring virtual fans to the stands during its summer games. 

But the most significant factor increasing daily user numbers is that companies have already invested in Microsoft. The company has 258 million paid seats for Office 365, which includes access to Teams.

As company workforces become more distributed, employees increasingly rely upon Teams for collaboration, chat, internal calling, and meetings.

However, when it comes to external, public switched telephone network (PSTN) calls remote employees need to place, they usually have no choice but to reach for their home phones and personal mobile devices.  

But there is a way to keep these external voice calls all within the Teams apps.

MetTel offers two Microsoft Teams External Voice options.

MetTel Direct Routing–PBX Replacement

This cost-effective solution makes Teams your primary source for calls while eliminating the need for your PBX and desktop phones. Direct Routing allows external (PSTN) calling by connecting Microsoft’s system to MetTel’s SBC using SIP Trunks.

With MetTel’s plan, employees make calls exclusively using the Teams mobile or desktop application using Microsoft’s PBX. But you can stay with the tradition of desktop phones if you’d like—MetTel offers Poly CCX series desktop phones for Teams calling.

MetTel Direct Routing Features

  • Flexible pricing – Just buy the SIP trunks you need and only pay for the minutes you use. 
  • User friendly – Employees can keep their current phone numbers and use their desktop apps, mobile apps, or desktop phones. 
  • Advanced features – Get call recording, auto-attendant, and real-time call analytics.
  • Easy setup – MetTel engineers do the heavy lifting.
  • Regulatory compliance – MetTel navigates clients through complex E911 regulations.
MetTel Integrated Routing – PBX Augmentation

Some companies aren’t quite ready to eliminate their existing PBX. MetTel offers a way to augment your current system with Teams. In these cases, companies would bring on MetTel Cloud PBX in addition to their existing PBX.

With MetTel Integrated routing, employees can make calls through the Teams app or their existing desktop IP phone. Incoming calls ring simultaneously through their PBX phone and Teams application. 

The big difference between MetTel Direct and Integrated is that Integrated Routing uses shared call/line appearance and MetTel connector to integrate external (PSTN) calling from PBX into Microsoft Teams.

Integrated Routing Features

Single number reach – Answer calls on a handset or through the app—incoming calls ring to both.

Keep existing features – Continue using your legacy systems’ features, and get call recording, auto-attendant, and real-time call analytics for Microsoft Teams.

Final Steps to Completely Cut Ties with Legacy Phone Systems

Even after migration to Teams for all voice calls, many companies still rely upon plain old telephone lines (POTS) for some services. These are voice and data services that traditionally require analog dial tones, such as alarms, elevators, and fax machines.

In the past, migrating these services would have been overwhelming. But MetTel has streamlined the process for our customers.

MetTel has built a solution, POTS Transformation, to completely transform all traditional phone lines for voice and data services that previously had been on copper lines. With this fully managed service, from deployment to replacement, MetTel oversees the entirety of the migration process.

MetTel POTS Transformation includes:

  • Turn-key deployment, including managed equipment and professional installation
  • Business continuity, even during network outages
  • Ongoing management from 24/7/365 US-based NOC monitoring and support
