BASKING RIDGE, NJ, and CUPERTINO, CA — Verizon Wireless today announced the successful completion of technical trials of 4G LTE IP Multimedia Subsystem (IMS) powered voice, video and mobile content sharing services using the Ecrio client framework. Verizon Wireless selected Ecrio’s IMS client application framework in 2009, and the product has since been qualified and embedded in a range of mobile devices in preparation for launch across the Verizon Wireless 4G LTE network.

The trials signal progress toward proving the technology and value of rich communication services (RCS) and media applications that are compelling for customers using Verizon Wireless’ 4G LTE network. Working together, Ecrio with its SIP/IMS service clients, and Verizon Wireless continue to bring RCS applications closer to market.

“This is indeed an exciting milestone in our relationship with Verizon Wireless,” said Tad Bogdan, Ecrio chief executive officer. “Ecrio is committed to both product innovation and continuing to work closely with Verizon Wireless and its device suppliers to integrate the client functionality needed for deploying successful end-to-end services. LTE has become the technology of choice for 4G deployments and Verizon Wireless is leading the way with the first broadly deployed LTE network. Ecrio is delighted to be working with Verizon Wireless to extend the bounds of mobile communications.”
