Business SMS From Your VoIP System For UK Businesses
Can you really send business texts straight from your phone system?
Yes. And let’s be honest. If you are not doing it yet, you are making it harder for customers to reach you.
Business SMS from your VoIP system is changing how UK businesses talk to customers. Faster replies. Higher open rates. Less friction. All from the same hosted VoIP or cloud PBX system you already use for calls.
With the PSTN switch off landing by January 2027, many UK businesses are moving to VoIP phone systems for UK businesses. If you are upgrading anyway, adding SMS makes sense. At Cleartwo, we roll this out with managed setup, UK based support and enterprise features at SME pricing. That is where it gets powerful.
What Is Business SMS From Your VoIP System And How Does It Work
Traditional SMS from a mobile is fine for personal use. But for business telephony UK, it feels outdated.
Business SMS through VoIP means your text messages are sent over the internet, just like your calls. Instead of using a mobile network, your hosted VoIP or cloud PBX routes messages through an SMS gateway linked to your business number.
Your office landline number can:
- Send text messages
- Receive replies
- Trigger automated alerts
- Sync with your CRM

Why Business SMS From Your VoIP System Is A Game Changer
Here is the stat. SMS open rates sit around 98 percent. Email is much lower. That alone should get your attention.
When SMS sits inside your cloud PBX or UCaaS platform, it becomes part of your daily workflow. Not a random extra app. That is the vibe.
What This Looks Like In Real Life
- Appointment reminders
- Delivery updates
- Missed call follow ups
- Payment links
- Marketing campaigns
- Internal team alerts
- Two way support chats
A customer calls after hours and misses you. They instantly get a text saying, We missed your call. How can we help. That small move can win you business. No cap.
Because it sits inside your business telephony UK platform, it links with call recording, reporting and CRM integration tools. That is real momentum.
How Business SMS Supports The PSTN Switch Off
The PSTN switch off is happening. By January 2027 analogue lines are gone.
If you still use an old PBX with no digital features, you are already behind. Moving to hosted VoIP or SIP trunking is step one. Adding SMS is step two.
Our guide on PSTN migration for UK businesses explains what to do. Once you move to IP based telephony, adding messaging is simple. You are no longer tied to copper lines. Simple as that.
Microsoft Teams Phone And SMS Integration
If your team lives in Microsoft 365, this gets exciting.
With Microsoft Teams phone integration and Direct Routing, you manage calls inside Teams. With the right VoIP provider, SMS can connect into that wider flow.
- Click to text
- Automatic CRM logging
- Instant missed call follow ups

This is full UCaaS energy. Calls. Texts. Collaboration. All synced.
Compliance And GDPR For Business SMS
Now let’s talk compliance. This matters.
In the UK, business SMS must follow GDPR and PECR rules. That means:
- Clear opt in consent
- Simple opt out options
- Secure data handling
- Proper audit trails
A strong cloud PBX with SMS and call recording makes this easier. Messages log automatically. CRM integration keeps everything organised.
If you care about compliant call recording for UK businesses, SMS compliance fits naturally into that setup.
Real Cost Savings For UK SMEs
Let’s be honest. Budget matters.
Traditional mobile texting for teams adds up. With bulk business SMS through VoIP, you often pay between 1p and 4p per message depending on volume. Combine that with up to 60 percent savings versus legacy systems and the numbers look strong.
Reviewing costs? See our guide to business VoIP system pricing in the UK. It shows where savings come from.
One platform. One bill. Less admin. That changes how you work.
