This brings to 150 the total number of people the VoIP equipment maker has laid off since December 2008.
Sonus executives said the action marks yet another in a series of restructuring efforts.
“This latest action is part of our plan to ensure the business is aligned to the company’s long-term strategic direction,” Richard Nottenburg, president and CEO of Sonus Networks, said in a prepared statement. “We are actively investing in our solutions portfolio to build a stronger and more competitive company, and will continue to deliver innovative, market-leading technology to our customers.”
The layoffs will be done by the end of the first quarter.
