West Corporation announces the completion of its acquisition of Smoothstone IP Communications, adding to its market-leading unified communications portfolio. Smoothstone is now part of InterCall in West’s Unified Communications operating segment.

Smoothstone is a leading provider of cloud-based communications for the enterprise. They deliver highly flexible and scalable solutions for clients’ next-generation IP telephony needs. Infonetics, the international market research and consulting firm, recently ranked Smoothstone among the leaders in its third annual North America Business VOIP Services Leadership Scorecard. Smoothstone enjoys a unique position among the companies ranked in the study as the only industry player focused on the enterprise market. The report noted that Smoothstone’s continued growth has been fueled “due to a strong focus on execution and its success in driving new customers onto its hosted VOIP platform, resulting in the second largest installed base of seats in 2010.”

“We are excited to be joining West and believe that together we can accelerate Smoothstone’s growth,” said Jeff Wellemeyer, co-founder and president of Smoothstone. “The combined companies have unprecedented experience in deploying unified communications solutions from mid-market companies to the largest enterprises. Both also have deep expertise in the deployment of both Cisco and Microsoft environments.”

“The acquisition of Smoothstone positions us as the leader in the enterprise unified communications marketplace,” said Todd Strubbe, president of West’s Unified Communications operating segment. “Together, we are able to help our clients speed the deployment of unified communications applications and services while helping to minimize the costs, complexities and risks of deploying new technology in dynamic business environments.”

The Smoothstone product portfolio will be available to West’s large base of clients, adding cloud-based IP telephony to a growing list of unified communications solutions. Smoothstone will continue to offer its full portfolio of applications and services, and will continue in its mission to help leading enterprises transform the way they communicate.
