    We’ve been using Numbergroup’s cloud hosted communication platform since 2016. Their cloud phone system is reliable and easy to use, plus they have extremely competitive call rates, friendly customer service and faultless support. Our switch to Numbergroup saved us over £800 a year! We highly recommend Numbergroup to all our business partners and clients.

    It’s been almost a year since we started using Numbergroup’s cloud services. Since the start they’ve made our lives easier by providing proper solutions, not just work-arounds. We’re in the recruitment business and telephone communication is the backbone of our business. I can’t say enough how relieved I am for choosing VoIP services from Numbergroup.
