Frequently Asked Questions
Your questions, answered.
In what countries does Callroute provide service?
Callroute is a global cloud service with presence across Europe, the USA, and Asia. For customers bringing their own carrier, Callroute services are available worldwide.
For customers who wish for Callroute to also provide phone numbers or PSTN access, availability depends on local telecommunications regulations. Please contact us to discuss your specific requirements.
How small or large can Callroute scale?
Callroute is a pure SaaS platform that scales effortlessly to meet your needs — from a single user and phone number to deployments of over 100,000 users. There are no technical limits to scale, and the same powerful application experience is available regardless of your organization’s size.
Does Microsoft Teams or Webex Calling integrate smoothly with our existing PBX?
Yes. With Callroute, all your phone numbers are managed in one place and can be easily assigned to your PBX, Microsoft Teams, or Webex Calling.
Calls between Teams, Webex, and your PBXs — or even between multiple PBXs — stay on-net across Callroute’s global network, keeping traffic secure and avoiding international carrier charges. This delivers major cost savings and seamless connectivity when your systems are in different countries.
What are the total costs involved, and how does it compare to our current telephony system?
If you’re already using Microsoft Teams or Webex Calling, good news — both platforms include native calling features (such as Teams Phone in Microsoft 365 E5). However, these don’t provide external PSTN connectivity. That’s where Callroute comes in.
We offer flexible, competitively priced calling plans with shared inclusive minutes, delivering better value than native Microsoft or Cisco calling plans. Each plan includes number rental, minutes, setup, and management for one predictable monthly cost.
Callroute is priced per user that’s enabled for dial tone through Callroute, or per concurrent voice channel when connecting to existing PBXs or SIP systems. If you prefer to bring your own carrier (BYOC), you simply pay for the Callroute middleware (app) — with no phone number rental or call minute charges.

What is your experience and expertise with Microsoft Teams Phone and Webex Calling implementations?
Callroute has been delivering enterprise voice solutions for over a decade. Since our founding in 2011, we’ve specialised in Cisco telephony and Webex Calling, and in 2018, we expanded our expertise to include Microsoft Teams Phone.
Today, we connect organisations around the world — from the UK to Australia and Brazil — using our deep experience across both Cisco and Microsoft ecosystems.
Our experts provide seamless deployments, reliable support, and proven best practices built on years of hands-on experience. That’s why customers trust Callroute to deliver scalable, high-quality voice solutions that just work.
What levels of support and managed services do you provide during and after the deployment?
For small and medium-sized businesses, all our plans include a fully managed service. We handle everything from the initial setup and configuration of Teams Phone to number porting and ongoing administration. This means you can focus on running your business without the hassle of managing your phone system, dealing with multiple providers, or taking time-consuming training courses.
For large businesses and enterprise organisations with their own IT teams, we offer both managed and unmanaged options. With our unmanaged service, you gain access to our intuitive self-service portal, allowing you to efficiently manage all your Teams Phone numbers and users in one central location, making administration simple and stress-free.
Can you provide references or case studies from organisations similar to ours?
Of course! Speak to one of our account managers about your business and they’ll be able to provide you a reference that closely matches your organisation.
How do you ensure the solution is customised and scalable to meet our specific business needs?
Callroute gives your team the tools to take control. We provide free, hands-on training throughout your entire lifecycle, showing you how to build, configure, and manage your own setup.
You’ll learn best practices for connecting SIP trunks, Teams, and Webex environments, and for managing your phone number inventory efficiently using metadata and categorisation.
If you’d rather have everything handled for you, Callroute can also be delivered as a fully managed service. But once you see how easy it is to make changes and add services yourself, you’ll realise it’s often quicker than sending us an email or picking up the phone.
