Through the Microsoft 365 Business Voice add-on for Microsoft Teams, you can add the ability to make and receive calls to Teams turning it into a complete Unified Communications platform.

With Microsoft 365 Business Voice you can replace your existing on-premise or cloud VoIP system and use the Microsoft Teams app for calling removing the need to work with multiple different platforms for core communications. If some or all of your users would still like to retain a physical handset for calling, there are a number of difference devices certified for Microsoft Teams.

As standard with Microsoft Teams you also get access to instant messaging, collaboration tools and video conferencing.

Pricing for Microsoft Teams with a UK Calling Plan (1200 monthly minutes per user to UK landlines and mobiles) is just £12/user/month.

You can also add on international calling bundles starting at £6/user/month for 600 minutes.

Direct Routing is where the Microsoft Teams interface is used for end users and system administrators but calls in the back end are routed through a third party. The benefits of doing this are: 

  • More cost effective than Microsoft Teams calling plans  
  • UK based customer service and support 
  • Improved resilience with built in business continuity options such as automated call redirection when there are outages, or a user does pick up 
  • Better experience porting existing phone numbers

Our approachable staff will use plain English and not confuse you with technical jargon. We will never make you sign a long contract and we guarantee to respond within an agreed timeframe. And we will never oversell and will always work on the principle of ‘best advice’.

We have partnerships with major suppliers such as Microsoft, Watchguard, Dell and so on, and as such we can offer both the hardware and software necessary to deliver the support, services and solutions you need to run your business. We aim to be the single point of contact for supplying these products and services, as well as taking on the responsibility of managing these assets once in place. However, this is not a mandatory requirement. Our clients are free to source and purchase their own hardware and software if preferred, and Labyrinth Technology is always on hand to offer as much (or as little) advice to help them decide what options suit their business.

As we always try to make clear, Labyrinth Technology provides IT support to our clients so that they no longer need to waste time dealing with IT problems. Instead, they can focus on making their businesses succeed. And as they succeed they do so confident that our services are fully scalable. We regularly review the service provided to our clients, both through data gathered from our best in class monitoring systems, as well as meetings with our customers. We can easily amend the products and services applicable to the contract, or can even move a client to entirely new support package.

We can help with the move AND the security needed as well! We’ve helped businesses work in a more agile fashion, including supporting remote workers by ensuring an on-demand supply of computers, along with networking, Wi-Fi and cloud facilities, and the software needed to make sure your remote workforce remains productive, as well as totally secure. Indeed we recently carried out a project to dial in to all of the home Wi-Fi routers of a client’s staff to determine the strength of security in place.

Our services are primarily aimed at business located with their main offices in the Greater London area, but our services are available for multi-site clients with locations across the UK.
