Azure-hosted SBC for Microsoft Teams

Enable Direct Routing for Microsoft Teams from the Azure Cloud

Organizations around the globe are moving to Teams for video conferencing, file sharing and chat.  Ribbon makes it easy to extend those capabilities by securely connecting Teams to an external telephone network, turning Teams into the office phone system.  Organizations can immediately move some or all of their business phone calls to Teams or slowly migrate off of a legacy PBX, depending on their needs.  And since Teams clients work on a PC/Mac or smartphone, users can make and receive calls from almost anywhere, on any device, staying connected and productive.

The key is Ribbon’s Session Border Controller, Software Edition (SBC – SWe Lite). It lives in the Azure Cloud and provides a secure bridge between your enterprise network and a Communication Service Provider (CSP).  There is no hardware to deploy or manage, as everything is in the Azure Cloud. The solution is operational in minutes and can scale up or down as needed.  Ribbon even offers a 30-day trial license so your organization can try it out.

  • Microsoft-certified
  • No hardware to install
  • 30-day trial license
  • Full media services
  • Robust security to keep bad actors out of your network
  • Choose your Communications Service Provider (AKA phone company)

Ribbon’s SBC software is designed for compute efficiency.  In fact, a small business can be supported with a single Standard_B1ms virtual machine instance on Azure.

What Do I Need to Get Started with Teams Calling?

Getting started is easier than you think, here are the 4 key requirements:

  1. Microsoft Phone System license in Microsoft 365 (typically included in the E5 package and an add-on for E3 – check your contract for details).
  2. A Communications Service Provider that can provide SIP Trunks for Teams (AKA a dial tone provider). SIP Trunks are the industry term for what Microsoft calls Direct Routing. If you choose a new dial tone provider, you will need to either port your existing phone numbers to the new provider or get new phone numbers (the provider can offer details and timing for each option).
  3. A Microsoft-certified Session Border Controller to terminate the SIP Trunks (Ribbon’s Software Edition – SWe Lite session border controller is fully certified). The SBC acts as a voice firewall and can mitigate interoperability issues.
  4. A trained staff member or an IT professional that can assist with set-up of the solution.

What is the SBC’s Role in Direct Routing?

Microsoft requires a certified SBC to act as bridge between Teams and the telephone network.  The session border controller provides multiple functions:

  • Security – it acts as a voice-aware firewall and encrypts traffic to protect the voice traffic itself and to prevent bad actors from entering the data network via the voice network
  • Interoperability – not every SIP Trunking provider is identical, Ribbon’s SBCs can adjust key parameters to make set-up easy and trouble-free
  • Legacy Connectivity – many organizations still have analog phones, elevator phones, door phones and fax machines.  Ribbon’s hardware–based SBCs have analog ports (FXS) to keep these assets working for years to come
  • Migration – often organizations want to slowly migrate to Teams, keeping their legacy PBX in place for weeks or even months or years.  Ribbon SBCs can provide simultaneous ringing so that both Teams and the old PBX share connectivity.
  • Resiliency or Fail over – Ribbon SBCs have multiple options to manage disruptions in service depending on the deployment model.  These tools can keep your organization connected even if the unexpected happens.

Hardware Instead of Software? – Sure

Ribbon’s SBC Software Edition Lite (SWe Lite) is full featured and is enabled in the Azure Cloud in minutes. However, there are reasons why an organization might prefer to locate an SBC in their own data center or use a turnkey appliance. Ribbon lets organizations choose the deployment model that’s right for them. The same software is available.

  • In the Azure cloud
  • As a software image for a virtual machine (SWe Lite)
  • Preloaded on Ribbon’s own hardware (Ribbon’s SBC 1000 or SBC 2000)

The software is the same, it’s simply a matter of deployment preference. If a Teams migration requires migration of a legacy PBX or analog devices (elevator phones, door phones, fax machines, etc.), a Ribbon SBC 1000 or SBC 2000 appliance has the added benefit of providing physical ports.
