Microsoft Teams has become the hub for meetings, messaging and collaboration across UK businesses. But when it comes to using Teams as a phone system, things can quickly become confusing.
Some businesses are still struggling to understand what Teams voice means, and whether they still need a phone system. The impending PSTN switch-off is also a factor when thinking about the future of telephony and voice.
UK businesses need a clear explanation of Microsoft Teams voice, and partners need to understand how working with the right provider unlocks more opportunities.
What do people really mean by Microsoft Teams voice?
The standard version of Microsoft Teams includes chat, meetings and collaboration. External phone calls, such as calling customers, suppliers or mobile numbers, aren’t included out of the box.
To use Teams as a business phone system, businesses still need:
- Business phone numbers.
- Access to the public phone network.
- A voice carrier to route calls.
- Ongoing support, resilience and compliance.
That’s where most of the confusion starts. Teams is the interface that users see, while voice calling is the service underneath.
What businesses need to understand is that Microsoft Teams isn’t replacing the need for a voice provider. Instead, the platform is changing how voice is delivered.
How can businesses add calling to Microsoft Teams?
There are three main ways businesses enable phone calls in Teams. All of them work, but each one is best suited in specific business environments.
- Microsoft Calling Plans
Calling Plans are purchased directly from Microsoft and bundle minutes with Teams. They can be suitable for very simple environments, but for many UK businesses, they come with limitations. There’s less flexibility around numbering, and limited control over call routing.
With fewer options for multi-site estates, alongside less support for legacy migration, businesses tend to look at alternatives.
- Direct Routing
Direct Routing allows organisations to connect Teams to a voice carrier using additional infrastructure.
While it does offer more flexibility compared to Calling Plans, Direct Routing can introduce more technical complexity. Businesses will need to be responsible for ongoing infrastructure management, which brings higher operational overhead.
- Operator Connect
The third option, Operator Connect, connects Microsoft Teams directly to a certified voice operator’s network. There’s no additional infrastructure to manage, and voice behaves like a cloud service rather than a traditional phone system.
For most UK organisations, Operator Connect is now the simplest, most scalable way to enable Teams calling.
Operator Connect explained
Operator Connect is Microsoft’s way of letting businesses bring carrier-grade voice directly into Teams. Rather than Microsoft acting as the phone provider, a UK voice operator delivers:
- Phone numbers.
- Call routing.
- PSTN access.
- Resilience and service quality.
- Regulatory and compliance responsibilities.
Users make and receive calls inside Microsoft Teams, using a combination of desk phones, headsets and mobiles. From a user perspective, nothing changes. But from an operational perspective, everything becomes simpler.
Operator Connect transforms voice into a managed cloud service – one that’s fully integrated with Teams.
Why does Operator Connect matter for UK businesses?
Voice has become a network and compliance issue, rather than solely an application issue.
Right now, most organisations are contending with various challenges. The PSTN switch-off, for example, is making the move away from legacy systems more pressing. For those operating across multiple sites and managing large estates of phone numbers, future-proof telephony is a must-have.
Inbound calls, especially for SMEs fighting for market share, are critical to long-term success. A fragmented network only introduces risk and puts these smaller businesses in an even more difficult position.
Operator Connect is specifically designed to handle this reality. Instead of businesses or IT teams carrying responsibility for voice infrastructure, that responsibility sits with the operator.
Rather than forcing a ‘rip and replace’ approach, voice can be migrated in a controlled, predictable way, while staying aligned to how the business operates.
This makes Operator Connect particularly well suited to those businesses looking to migrate their legacy systems. Organisations running across multiple sites, or ones operating hybrid working models, need that extra layer of support to maintain communication. An always-on support function mitigates the risk of downtime and preserves long-term revenue prospects.
Operator Connect vs ‘DIY’ Teams voice
One of the biggest differences with Operator Connect is accountability. With some Teams voice setups, responsibility can become fragmented. Microsoft would be the ones covering the application, another provider covers the network, and another provider manages the numbers.
It’s IT teams who’ll be the ones having to coordinate the issues.
With Operator Connect, one provider owns the voice service end-to-end. Call quality, routing and PSTN access all sit together, and issues are resolved faster with a more streamlined provider ecosystem. Above all, it reduces complexity.
What to look for in a UK Operator Connect provider
Not all Operator Connect providers are the same. When assessing options, UK businesses should look for:
- A Microsoft-certified Operator Connect provider.
- Proven UK voice network capability.
- Experience migrating complex estates.
- Support for multi-site and multi-number environments.
- Clear accountability for service, compliance and support.
Voice is still business critical. Operator Connect works best when it’s delivered by a provider that understands both Microsoft and the UK telecoms landscape.
Microsoft Teams voice’s place in a wider communications strategy
Microsoft Teams voice shouldn’t sit in isolation. For most organisations, it needs to work alongside cloud telephony, connectivity, security and resilience, and CX tools.
That’s why many businesses are moving towards network-led communications. Voice, connectivity and collaboration are designed to work together, rather than being stitched together from multiple suppliers. It’s down to partners to be able to provide such a seamless infrastructure.
Microsoft Teams has changed how people work, but voice still underpins how businesses communicate. Operator Connect allows Teams voice to be delivered with the reliability, control and accountability UK businesses expect, without adding needless complexity or risk.
