Frequently Asked Questions
Your questions, answered.
Does Microsoft Teams Phone integrate smoothly with our existing IT infrastructure and software applications?
If your organisation already uses Microsoft Teams for chat and meetings, you’re well on your way to unifying collaboration and calling services into a single, streamlined platform, you’re 75% of the way there.
Activating Teams Phone requires no additional installations or hardware for your employees. The phone dial pad will appear automatically in their Teams client, and they can continue using their existing headsets for both meetings and phone calls.
Microsoft Teams Phone is designed for seamless business integration, offering robust features to enhance customer communication. These include auto attendants with IVR options, call queues with “keep my place” functionality, consultative transfers, business voicemail, and AI-powered capabilities like call summaries to improve efficiency.
What are the total costs involved, and how does it compare to our current telephony system?
If you’re already using Microsoft Teams, here’s some good news: if you’re on a Microsoft 365 E5 licence, Teams Phone is included. However, this doesn’t provide the connectivity needed to make external phone calls, that’s where we come in as your Teams Phone provider.
We offer competitive calling plans tailored to businesses of all sizes, with inclusive minutes that can be shared across your entire team, rather than allocated per user. This delivers a better ROI compared to Microsoft’s native calling plans. Our plans include everything; number rental, calling minutes, setup, and management, at a fixed monthly cost for in-plan usage, simplifying your budgeting process.
If you’re not using the E5 licence, there’s no need to worry. A Teams Phone licence can be added to any Microsoft 365 plan, from Small Business Basic to E3, ensuring flexibility for your organisation.
Is the system flexible enough to accommodate our business growth and changing communication needs?
Microsoft Teams Phone is a cloud-based telephone system seamlessly integrated into Microsoft 365. If your organisation already relies on applications like Outlook, Word, Excel, or Teams, enabling Teams Phone as your business phone system is a logical step to streamline operations.
Not only does Teams Phone integrate effortlessly with the tools you already use, but it also empowers your business to expand into new markets, enhance customer service, and boost employee satisfaction. With Teams Phone, your workforce can stay connected anywhere in the world, on any device, whether it’s a laptop or mobile.
It takes business portability to the next level, offering capabilities that traditional systems simply can’t match. And if you’re adopting or considering Microsoft Copilot AI, integrating Teams Phone ensures that Copilot can provide comprehensive insights into customer interactions across email, webchat, and phone calls, giving you a competitive edge in understanding and improving customer relationships.
What is your experience and expertise with Microsoft Teams Phone implementations?
At Callroute, Microsoft Teams Phone is at the heart of everything we do. Since 2018, we’ve specialised in enabling Teams Phone for organisations across the UK and beyond, and we’ve been refining our expertise ever since.
Over the years, we’ve connected businesses as far afield as Australia and Brazil to Teams, leveraging our unique technology and experience to deliver seamless solutions.
As a company deeply embedded in the Microsoft Teams ecosystem, we pride ourselves on providing outstanding UK-based support and delivering exceptional value by truly understanding our customers’ needs. This dedication has earned us a strong reputation and a high customer retention rate.
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?
We’re not here to simply sell products, we’re here to build strong, collaborative relationships and establish a trusted partnership that delivers mutual value.
It all starts with understanding your organisation, how it operates, your customer offerings, and your goals for the future. We take the time to deeply analyse your business processes, identifying opportunities to streamline operations and design a modern Teams Phone configuration tailored to your needs.
We’ll build your call flows directly within your Teams environment, allowing you to test and refine them before going live. Once you’re satisfied, we’ll handle the number porting from your current provider and ensure a smooth transition.
From there, our managed services team will continue to support you, fostering an ongoing partnership that adapts your Teams Phone setup to your evolving business requirements.
