In 1995, CSTs founder Peter Hutchinson introduced restaurant paging to the UK hospitality market. Already widely used in the US, many leading restaurant chains quickly embraced the technology. His family soon joined Peter to help with the rapid expansion needed to meet the ever-growing demand. In 2000, the company was reorganised as Call Systems Technology Limited. CST's diverse range of cutting-edge communication systems enabled access to new markets, including retail, hotels, marine and the commercial sector.

With over 25 years of experience and working with an international partner network, providing thousands of systems each year to a wide range of industries, CST can rightly claim to be a world leader in on-site communications.
