Landlines are going digital

The British-built digital answer to the country’s legacy landline telephone network.

Upgrade your business phone system today

In 2025 the UK’s PSTN network will shut down, meaning 2.4 million businesses who use a copper landline or ISDN phone system will need to switch to an VoIP solution like CallSwitch One.

Take calls from anywhere

Our intuitive mobile and desktop apps help you bring your work number wherever business takes you.

A range of numbering options

Transfer existing numbers, or choose from millions of local, national, memorable, or non-geographic options.

Cost effective calling

Enjoy a predictable monthly subscription that includes all features, numbering, and minutes bundles.

Retain existing phone numbers, or choose from millions of new ones

We know phone numbers are essential to every business. Transfer the existing numbers customers know and trust, or if you’re setting up a new business, choose from millions of local, national, non-geographic, or even memorable numbers to portray the desired regional or national business presence.

Take calls wherever you are with our easy to use applications

Your phone numbers are no longer tied to a single location. Simply use your existing devices to log into our mobile and desktop apps to make and receive business calls from wherever work takes you. Never miss an important customer call again.

Present a professional appearance, every time

Manage calls with ease, with call routing features including an auto-attendant to route callers based on the nature of their enquiry, with on-hold music, ring groups, voicemail-to-email, and call recording to help you keep a record of interactions.

Keep personal time personal with time-of-day routing

CallSwitch One includes an easy to use time-of-day routing tool so you can set your business days and open hours and route customer calls accordingly. Ensure that calls are managed outside of operating hours with call-forwarding or customisable out-of-hours messaging to keep customers informed until you’re ready to get back to them.

Leverage the power of our SMS platform

SMS remains one of the most effective ways to reach customers, whether it's a sales promotion to a bulk list of contacts or an automated response to confirm an individual appointment. The CallSwitch One SMS tool enables this and even includes a visualiser to show you what the message will look like for the recipient before you click send.
