Charterhouse Voice & Data's contract win from Creditsafe also bagged the London-based ICT provider record breaker status in 8x8's partner programme.
Charterhouse signed up the global business credit report provider just six weeks into a partnership with the US headquartered cloud comms firm.
The partner programme gives Charterhouse customers access to X Series, 8x8's platform which provides voice, video, collaboration and contact centre solutions in one system.
Charterhouse added 8x8 to enhance its Fusion cloud services portfolio.
“We had a gap in our portfolio for a pure cloud provider," said Charterhouse CEO Mark Brooks-Wadham. "We’ve already signed a customer in record time, and are looking forward to signing many more in the future.”
