Add Phone Calls to Microsoft Teams Without Overpaying
How do you add phone calls to Microsoft Teams in the UK without paying Microsoft's premium calling plans? You use Direct Routing or Operator Connect with a hosted VoIP provider. This gives you full PSTN connectivity inside Teams. You keep your numbers. You avoid high per user costs.
Think about it. Teams is already where your conversations live. Your chats. Your meetings. Your shared files. It feels seamless. But when someone needs to call a mobile or landline, you hit a wall unless you pay more.
Many UK businesses want simplicity. They do not want surprise costs.
Your Microsoft Teams phone system should feel cohesive. Not bolted on. With the right hosted VoIP solution, you can add phone calls Teams UK businesses rely on every day, without locking into Microsoft's calling plans.
At Cleartwo, we see this every week. UK companies want Teams voice. They also want control and fair pricing. As a fully managed UK VoIP specialist, Cleartwo designs, installs and supports cloud PBX integrations with 99.99% uptime and real UK based engineers. Every detail matters.
Why UK Businesses Want To Add Phone Calls To Microsoft Teams
The timing matters. The PSTN switch off is coming in January 2027. Traditional ISDN and analogue lines are ending. If you have not moved yet, you will need to.
You can read more in our ISDN switch off 2027 guide and follow the steps in the PSTN migration checklist for UK businesses. The message is clear. Cloud telephony is the future.
Option 3 Operator Connect
Operator Connect is a middle option. Approved carriers connect directly into Teams. You do not manage complex hardware. There is no on site SBC device.
It feels simple. Yet you still avoid Microsoft Calling Plan pricing.
Both Direct Routing and Operator Connect let you design your Teams phone experience around your business. Not the other way round.
The Real Cost Difference
Let us look at the numbers. Many UK SMEs save between 40 and 60 percent compared to traditional telephony when moving to hosted VoIP. When you connect this to Teams using Direct Routing, the savings can be strong.
Instead of bundled minutes, you pay competitive SIP trunk rates. Instead of limited features, you gain tools such as:
- Advanced call queues
- Auto attendants
- Wallboard analytics
- GDPR compliant recording
- CRM screen pop
- Mobile softphone apps
- Multi site routing
Your phone system shapes customer experience. It affects how your brand feels. It is not just about making calls.
