CallTower Acquires OneStream Networks

CallTower, an international leader in delivering cloud-based enterprise-class unified communications, contact center and collaboration solutions,  announced the acquisition of OneStream Networks, a Rochester, New York-based global leader in voice solutions.

In joining forces, CallTower will deliver a broader range of global communication solutions and services to existing and future customers. OneStream Networks’ global cloud-connected and premise-based SIP voice services include Cisco Cloud Connected PSTN (with Webex Calling, Cisco Unified Communication Manager [UCM] Cloud, Webex Dedicated Instance and Webex Contact Center), Zoom, Avaya, Genesys, NICE CXone and Microsoft Direct Routing.

The unified organizations deliver an enhanced international offering. OneStream’s international, in-region Microsoft Teams Direct Routing capabilities augment CallTower’s existing Operator Connect for Microsoft Teams to provide a robust global solution. The acquisition will deliver additional innovative communication pathways for cloud solutions with international data centers, increased service offerings and superior customer experience.

“The acquisition of OneStream Networks creates an exciting and strategic opportunity for our customers, partners and growth in providing multiple international, enterprise communication solutions,” said CallTower’s CEO Bret England. “The combination of CallTower and OneStream gives our collective customers additional communication solutions, as well as vast resources to implement, integrate and support those solutions. We are looking forward to quick integration, releasing further innovative global solutions, continuing to provide best-in-class customer experience and welcoming the OneStream employees as part of the CallTower family.”

Both companies receive high ratings by customers and partners on implementation and service, along with expertise in communication technologies and solutions. Together, CallTower and OneStream Networks have implemented and continue to support more than 750,000 users on cloud-based communication services, providing the foundation for exceptional future growth. The combined organizations empower business communications with 11 data centers: seven in the United States, two in Europe and two in Asia.
