"We have had CMM Telecoms look after our phone lines and mobile phones for a number of years now and have always found them helpful, efficient and extremely knowledgeable. From the staff out in the field to the internal support, someone has always been available to assist us when needed.

"We have been thoroughly impressed with CMM's customer service and ongoing advice and support. The One Net system has allowed us to unify our landline and mobile phones and has given us greater flexibility in addition to comprehensive usage reporting. The set-up process was relatively easy, given their support and expertise."

“A couple of years ago we decided to invest in a new telephone and broadband solution for our company. With a busy online department, head office and 15 stores we had to get the decision right. We asked five companies to present but we were really impressed by the straight-forwardness, openness and technical ability of the guys at CMM. Although CMM were the smallest company we met we gave CMM the order and we are so pleased we did. CMM are super responsive, always contactable and genuinely care about our business. Great service, thank you CMM”
