What sets Cavendish apart from the competition is its expertise, its people and its culture. We were pioneers of IP based telephony solutions in the early 2000s and were one of the first companies to provide SIP services in the South East.

We offer market-leading On-Premise and Cloud-based telephone systems, connectivity solutions and mobile services, backed by expert support staff, most of whom have worked for Cavendish for many years.

Our culture is one of working as a team, to deliver outstanding service and support to our customers, across the complete range of business telephony services.
