  • You’ll be part of a fast-changing industry that is shaping how we work in the post-pandemic world. We’re working at the cutting edge of the converged/unified communications, collaboration, and telecommunications industries.

  • You’ll be part of a remote-first global team. We’re remote first, all work from home and follow a philosophy of “sometimes life gets in the way of work, and sometimes work gets in the way of life”. So, ditch the commute and work more flexibly.

We are a global unified communications company specializing in mediation between voice and IT infrastructure.  Recently described by a NYSE analyst as ‘the de facto 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 12 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-labeled 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.
