(Reuters) - RingCentral Inc, a cloud-based business communications services provider, is working with an adviser after receiving takeover interest, Bloomberg reported on Wednesday, citing sources familiar with the matter.

The company’s shares jumped as much as 19.9 percent to hit a record high of $43.05 in morning trading.

RingCentral is likely to attract interest from technology-focused private equity firms and other cloud-based software providers, according to Bloomberg. (bloom.bg/2vm9eMd)
