Xerox, T-Mobile and Ribbon Communications are working through different stages of the M&A process.

Ribbon is moving forward with its plans to buy ECI Telecom Group, while T-Mobile is fighting regulatory opposition to its Sprint purchase and Xerox is locked in a struggle to buy HP.

Our latest M&A roundup is highly diverse in nature and features more than just vendors. December treated us to another master agent acquisition by the same company, and a top distributor came under the reign of a private equity firm. And that wasn’t the only private equity story; LogMeIn announced plans to go private.
