VeriSign was a successful internet security company that had a series of product lines that connected mobile network companies' text message networks together securely—in 2004, about 3 billion per day. VeriSign CEO Stratton Sclavos recognised that with VoIP products developing, the revenues could decrease, and so he hired Vernon Irvin as Executive Vice President and General Manager of VeriSign's Communications Services division to solve the problem. Irvin saw good but technical and expensive products, but saw the volumes of exchange over the system as the solution.
