About

We began our journey four decades ago, as a call accounting firm, with a commitment to serve our customers, according to our core values – authenticity, integrity and creativity.

Since then, our industry has changed dramatically as communication technologies have emerged at an ever-accelerating pace. We’ve faced new challenges around every corner. By listening to our customers and holding true to our values, we’ve stood the test of time. We’ve never stopped striving and we’ve never stopped innovating, to always respond to our customers’ needs, and keep them ahead of the curve. It’s how we’ve adapted, iterated, and grown beyond our roots in call accounting into a complete communications analytics and insights solution, fully integrated for the technology of today…and prepared for the technology of tomorrow.

Great people are the force behind our success at ISI, and that starts with our leadership team. Drawing from a diverse background of experience, we are united by a passion for innovation and excellence.
