C Spire, formerly Cellular South, has announced the acquisition of Callis Communications from Mobile Alabama. Callis Comm is a Broadsoft based unified communications provider who recently expanded as a facilities-based CLEC in the greater Mobile region.

C Spire is the nation's largest privately held wireless communications company, is based in Ridgeland, Mississippi and employs nearly 1,200. C Spire Wireless is owned by the holding company Telapex, Inc., which also owns Telepak Networks, a fiber provider in that region. Recently, C Spire announced plans to build a data center in Northeast Mississippi as well as an ambitious plan to deploy 1 Gbps ultra high-speed Internet access, called C Spire Fiber to the Home. This acquisition of Callis will be an added value to the FTTH project.

Hu Meena, president and CEO of C Spire, said, "In addition to the cloud-based solutions available today, we plan to provide a greatly expanded and comprehensive suite of world-class cloud based computing and enterprise application solutions from our new state-of-the-art tandem of data centers."

Financials details were not released.
