Depending on your individual needs, DoubleEdge can make the relevant assessments to offer you a range of integrations and add-ons from our valued technology partners, that help your business to operate “business as usual”, without the usual headaches associated with sending a workforce home.

Why Use Direct Routing?

Direct routing enables voice capability natively into MS Teams and all that is required is a Microsoft 365 or Office 365 license, MS Teams and an internet connection. Simply put, connection from MS Teams is via an IP connection, enabling full PSTN breakout on the telephone network, and can offer multiple benefits as an alternative to Microsoft calling plans:

  • Cost savings
  • Complete cloud solution
  • Increased functionality & security
  • Teams as your single collaboration client
  • Seamlessly port your numbers
  • Access to traditional call features on Microsoft Teams


With our Teams integrations, we can deliver not only carrier grade telephony, enabling full voice capacity, but also the options of compliance call recording for Teams, analytics, security and more, at a fraction of the cost.

Many of our clients operate within the finance, legal and public sectors and require the same security and compliance recording capabilities as they have for their office settings, in order for their employees to be able to work remotely, while continuing to comply with regulations such as MiFID II and FCA SYSC 10A.

Our compliance solutions can capture the following:

  • Voice & Video Calls
  • Audio & Video Meetings
  • Chat / Instant Messaging
  • Screen Share

We can provide the best solution for you and your business’s requirements, to ensure employees can continue working safely and effectively – not only now, but in the future landscape that could mean working differently and remotely long term.
