NEW YORK (CNN/Money) - Avaya Inc. said Monday it expects to miss second-quarter revenue and results estimates, plans to cut about 1,900 jobs and will sell about $90 million in stock to Warburg Pincus Equity Partners.

The Basking Ridge, N.J.-based communications equipment maker said it expects revenue in its quarter ending March 31 of between $1.24 billion and $1.275 billion, compared with its previous estimate of $1.254 billion to $1.358 billion. Analysts surveyed by earnings tracker First Call expected Avaya to earn $1.258 billion.

Avaya also said it expects to lose 6 to 10 cents a share in the quarter, compared with its previous estimate of a loss of 8 cents. Wall Street expected Avaya to lose 7 cents a share, according to First Call.

The company also said it plans to cut about 1,900 jobs as part of a restructuring that it hopes will save between $180 million and $200 million per year. Avaya will take a $100 million restructuring charge in the second quarter, along with a $130 million charge for converting preferred stock held by Warburg Pincus into common stock.

In addition to the conversion, Avaya will sell 14,383,953 shares to Warburg Pincus at $6.26 a share. Warburg Pincus executive Jeffrey Harris resigned from Avaya's board prior to the board's approval of the transaction.
