Transition is easy, we’ll even route Teams calls via your legacy PBX, so your users can retain their familiar handsets until they confident with Calling in Teams.

The Details

  • Costs
  • Risks
  • Benefits

We give you Domestic and International calling for just £5 per user per month – less than a third of the cost of Microsoft International Calling Plans. With real-time billing data, fraud detection, transport layer security and the best quality international calling routes, our Teams Direct Routing makes Phone System for Microsoft Teams a great choice for you and your business.

Whilst our global network of Microsoft Certified Session Border Controllers (SBC) are fully resilient, both your mail and phones rely on Office 365. But because we handle calls upstream of Microsoft, we’ll send them to your mobiles if you lose O365.

  • Lower cost than Calling Plans
