8x8 has acquired privately-held DXI for £16.5m and plans to bring DXI's EasyContactNow contact centre product to the US market by the end of 2015.
"The acquisition of DXI enables 8x8 to continue to boost its European expansion efforts," said Vik Verma, Chief Executive Officer of 8x8.
"With DXI's strong UK contact center market presence and technical team, 8x8 can broaden its European footprint, offer a frictionless, online sales approach for agile contact centres and line-of-business buyers, and add a stellar team passionate about bringing next-generation contact centre innovations to market."
Luca Pepere, DXI CEO, added: "Over the last couple years, we have seen an inflection point for cloud communications, and the contact centre continues to evolve from a stand-alone cost centre to a critical organisation-wide business asset.
"This market shift will propel the next phase of our business, and together we will drive a new level of disruption in business communications."
