Oldcastle Materials, North America's leading manufacturer of building products and materials selects SLA's ESChat to enable cellular Push to Talk communication for its fleet

ESChat is the leading carrier independent Push to Talk over Cellular solution, providing encrypted communication for the US Military, first responders and business users.

SLA and Oldcastle Materials today announced the selection of SLA’s Enterprise Secure Chat (ESChat) as Oldcastle’s cellular Push-to-Talk preferred solution. ESChat provides encrypted real-time push to talk (PTT), location tracking and group text messaging product that is carrier agnostic and features cross carrier communications.

During 2014, Oldcastle Materials deployed ESChat as part of a technology trial to evaluate the viability of ESChat as a replacement to traditional cellular Push to Talk service and conventional radio systems. Upon completion, Oldcastle determined that ESChat would be offered as the preferred cellular PTT solution to its materials transportation fleet.

“Oldcastle is able to leverage Android technology already deployed as part of its telematics solution. As such, we have been able to add ESChat without the need for additional capital expenditures plus a significant reduction in monthly service fees,” said Jack Delperdang, Director of Customer Service & Dispatch Operations for Oldcastle RMC. “In addition to enabling our mobile fleet, Oldcastle is also taking advantage of the ESChat PC based Dispatch Console that allows our dispatchers and management personnel to locate and communicate with the fleet.”

“We are honored to have been selected by Oldcastle Materials Group as their cellular PTT provider,” said Josh Lober, President of SLA Corporation. “SLA's ESChat is the most full featured real-time PTT product available today. As a carrier agnostic solution, Oldcastle is able to deploy a seamless nationwide communication network using the wireless carrier of choice for each region.”

First commercially deployed in 2008 at Edwards Air Force Base in California, SLA's suite of PTT products has since evolved to include encrypted group text & image messaging, as well as live and historical GPS location services. ESChat has grown into the solution of choice for secure cellular Push to Talk services for military, government and commercial business users.

The ESChat product suite supports Android and iOS smartphone devices and personal computers. ESChat also supports a Radio over Internet Protocol (RoIP) interface that allows it to be interfaced to first responder dispatch and Land Mobile Radio (LMR) networks providing a seamless and secure communication environment.

The ESChat product line benefits customers with AES-256 voice encryption, secure group text & image messaging, PC based dispatch clients, and gateways for tactical land mobile radio (LMR) networks.

ESChat is available on standard mobile phones, smartphones, personal computers and tablets, and is supported by on the Android, iOS, BREW, Linux and Microsoft Windows operating systems. ESChat service is currently available across North America for government and enterprise business customers.

Commercial customers can purchase ESChat from SLA Corporation or through channel partners including Verizon Wireless. Government customers can purchase ESChat direct from SLA or via GSA.
