Are your phone bills getting out of control? Are you sick and tired of dealing with a company whose customer service is nonexistent?

If so, you’ve come to the right place. At Numbergroup, we offer cloud-based telephony services to businesses in the UK, providing a full suite of communication solutions, including cloud telephony, numbering, call solutions and contact centre services. We’re committed to providing the highest levels of customer service and support. Our solutions are fully scalable and require no additional equipment or CapEx—just an internet connection.

This means that once you’re connected, there are no ongoing costs for installation or maintenance—you’ll only pay for what you use.

Our cloud-based system is more flexible and cost-effective than a traditional ISDN PBX phone system.

You won’t be tied down by expensive long-term contracts or locked into outdated infrastructures; instead, we’ll keep your business up-to-date and ready for whatever comes next in the industry.

Best of all? We strive to ensure that your business has access to reliable service 24/7/365—even if something goes wrong with your infrastructure or your internet connection, we’ll do everything we can to keep your calls flowing smoothly.
