If you’re planning on adding telephony functionality to Microsoft Teams, there are a handful of options available. Microsoft has its own (albeit basic) telephony capabilities which could be suitable for some brands, and there’s also Operator Connect for a managed service provider experience where you can choose your own carrier.
However, for most companies, the number one choice will be direct routing, a solution that allows brands to bring their preferred communication provider into Microsoft Teams. Direct Routing gives companies greater geographic reach and access to more flexible, bespoke communication technology than the Microsoft calling plans.
According to Microsoft, direct routing calling minutes grew eight times in 2020 alone and more than four times as many companies now use the service. The question is, which SBC providers are most worthy of your consideration when it comes to implementing direct routing?
Let’s explore some of the best SBC providers for Microsoft Teams voice.
The Best Microsoft Teams SBC Providers
Direct routing allows organisations to configure tailored communication strategies based on their individual needs through connections with Session Border Controller (SBC) providers. The number of SBC providers partnering with Microsoft to enhance Teams has increased drastically in recent years, but there are still some vendors who seem to outshine the competition, such as:
AudioCodes
One of the first companies to provide SBC technology for Microsoft Teams voice, AudioCodes is a fully-certified partner of Microsoft, delivering a host of ways for users to upgrade their Teams experience. With AudioCodes, you get a fully scalable solution with hybrid platform support, so you can easily integrate cloud-based and on-premises technology.
AudioCodes promises comprehensive and secure SIP connectivity, enhanced voice quality with SILK support, and centralised real-time voice quality monitoring. You’ll also be able to leverage local media optimisation with AudioCodes, which isn’t an option for all Teams SBC providers.
Ribbon
Leaders in the communication landscape, Ribbon offers a variety of Microsoft Teams direct routing and SBC solutions. You can explore Ribbon Connect for Microsoft Teams, making it easier to quickly migrate key sales staff into the environment. Ribbon also offers Teams service assurance so that you can monitor and manage network traffic.
Ribbon’s technology is great for companies needing to maintain a clear view of their Microsoft ecosystem with helpful analytics, and excellent service.
MetaSwitch (Now Microsoft)
Now owned by Microsoft, the MetaSwitch SBC Perimeta is a fully Microsoft-certified solution which can be deployed either in the Azure public cloud or in an operator network. The solution was specially designed to help companies leverage all the benefits of Teams without compromising communication quality, or security.
MetaSwitch’s SBC technology is available for use both through the Microsoft Teams direct routing environment and Operator Connect, making it unique in the current marketplace. This could be the ideal SBC provider for today’s transformative teams.
Cisco
Cisco’s Unified Border Element, or “CUBE” solution, is Cisco's comprehensive direct solution for Microsoft Teams. Certified with Microsoft Teams as of 2019, Cisco has a wide selection of CUBE SBCs available for business leaders to choose from.
