We are a global unified communications company specializing in mediation between voice and IT infrastructure.  Recently described by a NYSE analyst as ‘the defacto way to voice-enable Microsoft Teams’ we punch well above our weight.

Our core product is Call2Teams – a Microsoft approved middleware product that seamlessly connects any business phone system or SIP Trunk provider to Microsoft Teams. Call2Teams is a cloud-native, enterprise-grade and high-availability mediation platform that operates multi-tenant infrastructure in 4 continents across 6 Azure regions. We work with multiple Microsoft approved cloud-based SBC vendors and have interoperability with over 30 PBX/Call controllers and over 30 trunk providers.  The product is sold on a per user, per month SaaS basis and is sold only through channel partners.  We have over 275 channel partners, including providing a private-labelled service to most of the world’s biggest UCaaS and CCaaS providers. See for more information.

We recently launched a second product, Carrier Automate – a cloud service technology that bridges between Service Providers (telco operators and carriers) and Microsoft Teams.  Partnering with Ribbon Communications, we are one of only a handful of approved Microsoft Operator Connect Accelerator partners.  This product is in early life but promises to be as innovative and class-leading as Call2Teams. This is your chance to join us at the beginning of this exciting journey. See for more information.

We were founded in the UK in 2017 and have recently joined the DSNTY group. The business has seen hyper-growth in the last two years and has a product roadmap that will see this high growth continue. We are a fully remote team with employees in the UK, Europe and the US.

We are a tight-knit team determined to build great products.  If all this resonates with you, then we’d love to hear from you.
