CallTower has made a name for itself as a leader in offering its US customers the widest set of features and highest quality of voice calling through Direct Routing for Microsoft Teams.
Now they are taking their show on the road and enhancing their full technology stack internationally with the launch of local in-country Native Microsoft Teams Direct Routing UCaaS solution.
In May, CallTower announced that their Microsoft Direct Routing solution is now available in over 100 countries, enabling customers to access high quality voice calling for global landline and mobile through their Native Microsoft Office 365 Teams integration. All while keeping the calls local.
This move adds Direct Routing voice calling for Office 365 users in 30 more countries than is available through Microsoft itself. Microsoft does not offer Business Voice outside of the US, UK, and Canada, leaving Direct Routing as the only international solution for phone calling.
Bringing Service Closer to the Customers
Speaking with CallTower’s Chief Revenue Officer William Rubio, he tells UC Today that this launch will enable them to bring not only their high level of voice quality service to the international market, but a wide range of features that US customers have been benefiting from over the past few years. This includes CRM and Contact Center integrations, texting, and support for analog devices like overhead, paging, door buzzers, credit card machines, security gates, and the like. They are also launching a new receptionist console and enhanced call recording within Teams and Azure, adding to their existing package of features.

Powering this new rollout of US-level service is CallTower’s expansion to have a physical presence in a range of global data centers, increasing their proximity to customers for faster, higher quality data services.
These locations include the UK, Germany, Australia, and Singapore. For countries that require a local provider to handle voice calling like India and China, CallTower has teamed up with leading local organisations to offer service in those locations.
Rubio makes the point that CallTower is focused on optimizing service for each location, understanding that every country has its own specifications and requirements in order to offer the best service.
“What might work great for the UK might not work right for China, which might not work right for Australia,” he says, explaining that, “The good thing is that we have options in these locations to offer flexibility and work in the local contexts”
How to Know if Your Solution is Microsoft Native
A key differentiator that CallTower is bringing to its international customers in comparison with much of the competition is that their technology stack is the genuine Native Direct Teams Routing solution.
