Toll-free made easy explained

Who we are

We are the known leader in toll-free number provisioning and least-cost routing (LCR) with more than 100 carrier and RespOrg customers today. Our 8MS Cloud platform integrates with the Somos National Toll-Free Number database, SMS/800, as well as carrier and text aggregator systems, to simplify and automate toll-free provisioning and complex routing.

CSF began in 1988, co-founded by Clem Hergenhan and Steven Levinn, two accomplished engineers from AT&T Bell Labs. They established CSF as a custom software development firm and began the work of developing a client interface to SMS/800.

They later transitioned the business into a software company to evolve this client interface into a premier toll-free number provisioning system. Now, 8MS is deployed throughout the industry.

With the addition of the Aerialink messaging platform, we also offer enhanced and new texting solutions for RespOrg and enterprise customers. 

Now part of iconectiv, the company is profitable, stable, and growing. Customer loyalty is a hallmark of our business. In partnership with Somos and other industry leaders, we are committed to delivering the best toll-free number management and enabling capabilities to our joint carrier and RespOrg customers.

    “I’m a software developer; I work on the system architecture, design the API and screens, write the user documentation and provide customer support. But that’s not my job, that’s the steps in my job. Slick user interfaces with flashy and cool features aren't my goal; my goal is to build the features you need and to help you use them as easily, efficiently and quickly as possible. My job? It’s to help you succeed!”

    “Service means being a trusted partner and not just another vendor. It is reflected in the questions we ask and our willingness to explore options that are different from 'how it's always been done'. It's reflected in our transparency and honesty in working through issues... as that's how I would like to be treated if the shoe was on the other foot.”
