Vonage gains after report activist Jana pushing for sale or break up

Vonage Holdings (NASDAQ:VG) rose 5.3% after a report that activist Jana Partners is asking the company to explore alternatives, including a sale of all or parts of the telecom company.
Jana has discussed its beliefs with the company and fellow holders after a previous review process didn't result in a sale, according to a Bloomberg report.
Bloomberg reported in May that Jana built a stake in the company and was expected to push for changes.
Vonage announced in February that it was terminating the sale process for its consumer business after a nine-month review of the unit.
