Microsoft Teams has seen tremendous growth over the past two years, driving it to 270 million monthly active users.
The number of these users with voice plugged into their platform is not certain, but it’s widely thought to be incredibly low – creating opportunities for both Microsoft and experienced voice providers.
In fact, research from market analyst Metrigy shows “a clear preference” from businesses for maintaining a separate, third-party provider for voice – even when they are already using Teams for messaging, video, and collaboration.
Metrigy research found that doing so can provide several significant benefits to companies. These include lower costs, greater reliability, more features, and contact centre tools.
Businesses have two options when it comes to plugging voice into teams.
- Use services provided by a third party that can be integrated with Teams
- Use Microsoft’s own native voice service
Integration with a Separate Provider
Plugging third-party providers into Teams avoids using the Microsoft Teams Phone System, saving businesses money because they don’t need to purchase additional licensing.
Metrigy’s research found that businesses taking this approach spend on average £910 per user per year, compared to £1,139 for companies using the Teams Phone System.
This approach also gives businesses access to features beyond those offered by Microsoft, such as advanced analytics, IVR, and fax support.
Microsoft Phone System
The second option is to use Microsoft’s own Phone System. There are various ways this can work behind the scenes, with users then able to make calls from the native Teams dialler.
Businesses can buy call time from Microsoft itself through Teams Calling Plans or plug third-party services into Microsoft’s Phone System through Direct Routing or Operator Connect.
The Best of Both Worlds
RingCentral lets users bring the vendor’s services to Teams through both models.
RingCentral for Microsoft Teams lets businesses add RingCentral’s own dial pad into the Teams platform, allowing users to make calls from within Teams powered by the RingCentral application. Importantly, companies do not need to purchase any voice licensing from Microsoft.
RingCentral Cloud PBX for Teams is RingCentral’s Direct Routing offering. In this option, RingCentral provides the PSTN connectivity, with users making calls from Teams’ own dialler.
This second option was recently adopted by Howard Kennedy, a London-headquartered global law firm with 400 employees.
Howard Kennedy was looking to consolidate seven different platforms into one unified offering that would allow its employees to work more agilely.
This went from a preference to a necessity in March 2020 when lockdowns were put in place worldwide.
