Transera, provider of software that lets its clients set up cost-effective call centers with agents (in-house or outsourced) all over the world, announced that it brought in $17 million in a fourth round of funding from Accel Partners, Apax Partners, Lighthouse Capital Partners and Storm Ventures. The Sunnyvale, Calif.-based company says it will use the money to go after new customers, improve its service infrastructure and continue developing its products.

In particular, Transera’s software, called Seratel, makes it easier and cheaper to monitor remote agent-customer interactions. It counts the American Red Cross, Logitech, Office Depot and TiVo among its clients. The company has raised $30 million to date.
